Yasova, Temur Champion

Other Creatures you control have Trample.
At the beginning of combat on your turn, you may pay {u/r}{g/u}{r/g}. If you do, gain control of target creature an opponent controls with power less than Yasova, Temur Champion's power until end of turn, untap that creature, and it gains haste until end of turn.
Ferocious - Whenever Yasova or another creature with a power of 4 or greater enters the battlefield, deal 1 damage to target opponent for each creature you control.
