Vigilance

When Cataclysmic Gearhulk enters the battlefield, each player chooses an artifact, a creature, an enchantment, and a planeswalker from among the nonland permanents they control, then sacrifices the rest.

First strike

When Combustible Gearhulk enters the battlefield, target opponent may have you draw three cards. If the player doesn’t, you mill three cards, then Combustible Gearhulk deals damage to that player equal to the total mana value of those cards.

Menace

When Noxious Gearhulk enters the battlefield, you may destroy another target creature. If a creature is destroyed this way, you gain life equal to its toughness.

Flash

When Torrential Gearhulk enters the battlefield, you may cast target instant card from your graveyard without paying its mana cost. If that spell would be put into your graveyard, exile it instead.

Trample

When Verdurous Gearhulk enters the battlefield, distribute four +1/+1 counters among any number of target creatures you control.
