Flash Ward {2} Probing Telepathy — Whenever a creature entering under an opponent's control causes a triggered ability of that creature to trigger, you may copy that ability. You may choose new targets for the copy.

You may have this creature enter as a copy of any creature on the battlefield, except it isn't legendary, is an artifact in addition to its other types, and has myriad. (Whenever it attacks, for each opponent other than defending player, you may create a token copy that's tapped and attacking that player or a planeswalker they control. Exile the tokens at end of combat.)

When this creature enters, you may pay {1}. When you do, create a token that's a copy of target token you control not named Dutiful Replicator.

Flying You may have this creature enter as a copy of any creature on the battlefield with mana value less than or equal to the amount of mana spent to cast this creature, except it's a Bird in addition to its other types and it has flying.

Ward {2} As this creature enters, choose a creature type. This creature is the chosen type in addition to its other types. If a triggered ability of another creature you control of the chosen type triggers, it triggers an additional time.

You may have this creature enter as a copy of a creature or planeswalker you control, except it enters with an additional +1/+1 counter on it if it's a creature, it enters with an additional loyalty counter on it if it's a planeswalker, and it isn't legendary.

Shroud (This creature can't be the target of spells or abilities.) Whenever another creature dies, you may put a +1/+1 counter on this creature.

If an opponent cast three or more spells this turn, you may pay {0} rather than pay this spell's mana cost. Exile any number of target spells.

{T}: Target creature an opponent controls attacks you this turn if able.

This creature can't be blocked as long as defending player controls an artifact.

Trample; rampage 2 (Whenever this creature becomes blocked, it gets +2/+2 until end of turn for each creature blocking it beyond the first.) This creature can't be blocked except by three or more creatures.

As long as there are exactly three tide counters on this creature, it gets +1/+1. Whenever there are four or more tide counters on this creature, remove all tide counters from it.

Whenever a nontoken creature you control enters, if it doesn't have the same name as another creature you control or a creature card in your graveyard, draw a card.

Prowess (Whenever you cast a noncreature spell, this creature gets +1/+1 until end of turn.) When this creature enters, surveil 2. (Look at the top two cards of your library, then put any number of them into your graveyard and the rest on top of your library in any order.)

When this creature dies, reveal cards from the top of your library until you reveal a nonland card with mana value 3 or less. You may cast that card without paying its mana cost. Put all revealed cards not cast this way on the bottom of your library in a random order.

Trample This creature gets +10/+10 for each player who has lost the game. Whenever this creature deals combat damage to a player, you may mill that many cards. Put any number of land cards from among them onto the battlefield tapped.

Defender, flying {T}: Put this creature and each creature it's blocking on top of their owners' libraries, then those players shuffle.

This creature enters with three +1/+1 counters on it. {2}, Remove a +1/+1 counter from this creature: Put a +1/+1 counter on target creature. {1}, Remove a +1/+1 counter from this creature: Prevent all combat damage that would be dealt this turn.

Toxic 2 (Players dealt combat damage by this creature also get two poison counters. A player with ten or more poison counters loses the game.) When this creature enters, you and target opponent each create a Treasure token. Whenever an opponent sacrifices a noncreature token, that player gets two poison counters.

As long as this creature is tapped, creature spells you cast cost {2} less to cast.

Whenever this creature attacks and isn't blocked, you may have defending player activate a mana ability of each land they control and lose all unspent mana. If you do, this creature assigns no combat damage this turn and at the beginning of your next main phase this turn, you add an amount of {C} equal to the amount of mana that player lost this way.

When this creature enters, search your library for a basic land card or Cave card, put it onto the battlefield tapped, then shuffle.

{T}: Add one mana of any color. Whenever you expend 8, return up to one target permanent card from your graveyard to your hand. (You expend 8 as you spend your eighth total mana to cast spells during a turn.)

When this creature enters, exile up to one target non-Salamander creature. That creature's controller creates a 4/3 blue Salamander Warrior creature token. Encore {4}{U}{U} ({4}{U}{U}, Exile this card from your graveyard: For each opponent, create a token copy that attacks that opponent this turn if able. They gain haste. Sacrifice them at the beginning of the next end step. Activate only as a sorcery.)

{2}, Sacrifice this creature: Choose one — • Destroy target artifact. • Destroy target enchantment. • Draw a card. Then you may put a land card from your hand onto the battlefield tapped.

Affinity for tokens (This spell costs {1} less to cast for each token you control.) Whenever a token you control enters, tap target nonland permanent an opponent controls. It doesn't untap during its controller's next untap step.

Whenever an opponent casts a spell, you may exchange control of this creature and that spell. If you do, you may choose new targets for the spell. (If the spell becomes a permanent, you control that permanent.)

Put one onto the battlefield face down as a 2/2 creature and the other into your graveyard. Turn it face up any time for its mana cost if it's a creature card.)
