Beedle, The Merchant

At the beginning of each combat, creatures
you control gain first strike until end of turn if a creature you control has first strike. The
same is true for flying, deathtouch, double strike, haste, hexproof, indestructible, lifelink,
menace, reach, skulk, trample, and vigilance.

Horned Colossus Beetle?!" - Beedle
