At the beginning of your upkeep, put a shield counter on target creature an opponent controls. Whenever you put one or more counters on a creature you don't control, tap that creature and goad it. It gains trample until your next turn. (Until your next turn, that creature attacks each combat if able and attacks a player other than you if able.)

At the beginning of your end step, for each player, put a +1/+1 counter on up to one target creature that player controls. Each creature with one or more counters on it can't attack you or planeswalkers you control unless its controller pays {X}, where X is the number of counters on that creature.

Flying When this creature enters, support 6. (Put a +1/+1 counter on each of up to six other target creatures.) Whenever a creature with a counter on it attacks one of your opponents, that creature gains flying until end of turn.

{T}: Add one mana of any type that a land you control could produce. If this creature has a +1/+1 counter on it, add three mana of that type instead. {3}{G}{G}: Adapt 3. (If this creature has no +1/+1 counters on it, put three +1/+1 counters on it.)

Whenever you tap an untapped creature an opponent controls, you may pay {1}. When you do, choose one — • Create a 4/4 white and blue Elemental creature token. • Put a +1/+1 counter on each creature you control. • Scry 2, then draw a card.

When this enchantment enters, put a rejection counter on each creature your opponents control. At the beginning of your end step, for each opponent, choose up to one target creature they control with a rejection counter on it. That creature's owner puts it on their choice of the top or bottom of their library.

Whenever a creature an opponent controls becomes tapped, if it isn't being declared as an attacker, you may draw a card. {4}{U}: Tap target creature without flying.

Flying 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.)
