Menace, ward {2} If a creature you control dealing combat damage to a player causes a triggered ability of a permanent you control to trigger, that ability triggers an additional time.

Menace Whenever this creature deals combat damage to a player, if it has fewer than four +1/+1 counters on it, put a +1/+1 counter on it. Then if it has exactly four +1/+1 counters on it, search your library for a card, put it into your hand, then shuffle.

Backup 1, backup 1, backup 1 (When this creature enters, put a +1/+1 counter on target creature. If that's another creature, it gains the following abilities until end of turn. Each backup ability triggers separately.) Trample Whenever this creature deals combat damage to a player, put that many +1/+1 counters on it.

Devoid (This card has no color.) Whenever a creature you control deals combat damage to a player, you may draw a card. {3}{C}: Target creature can't be blocked this turn. ({C} represents colorless mana.)

Trample Toxic 1 (Players dealt combat damage by this creature also get a poison counter.) Whenever this creature deals combat damage to a player, proliferate. (Choose any number of permanents and/or players, then give each another counter of each kind already there.)

This creature can't block. Prowl {1}{B} (You may cast this for its prowl cost if you dealt combat damage to a player this turn with a Goblin or Rogue.) Whenever a Goblin or Rogue you control deals combat damage to a player, if this card is in your graveyard, you may return this card to your hand.
