Thrasios, Triton Hero

At the beginning of each player's upkeep, that player chooses target player who controls more creatures than they do and is their opponent. The first player may reveal cards from the top of their library until they reveal a creature card. If the first player does, that player puts that card onto the battlefield and all other cards revealed this way into their graveyard.

Whenever Bruse Tarl enters or attacks, target creature you control gains double strike and lifelink until end of turn. Partner (You can have two commanders if both have partner.)

Untap all creatures. Until end of turn, whenever a creature an opponent controls blocks, draw a card. Draw a card.

T: Add C. T: Each player gains control of all creatures they own.
