Flying, haste

Whenever one or more Dragons you control attack an opponent, goad target creature that player controls.

Whenever a creature deals combat damage to one of your opponents, if that creature had to attack this combat, you put a +1/+1 counter on Firkraag, Cunning Instigator and you draw a card.

When Grishnákh, Brash Instigator enters the battlefield, amass Orcs 2. When you do, until end of turn, gain control of target nonlegendary creature an opponent controls with power less than or equal to the amassed Army's power. Untap that creature. It gains haste until end of turn.

Attacking creatures you control get +1/+0.

At the beginning of each upkeep, if no spells were cast last turn, transform Instigator Gang.

, : Until your next turn, target creature an opponent controls can't be blocked. Goad that creature. (Until your next turn, that creature attacks each combat if able and attacks a player other than you if able.)

Double strike

Whenever Warren Instigator deals damage to an opponent, you may put a Goblin creature card from your hand onto the battlefield.
