Skartaj Wurmcrusher

Whenever another creature enters the battlefield
under your control, if it had trample, Skartaj
Wurmcrusher gains trample until that creature
leaves the battlefield. The same is true for flying,
deathtouch, double strike, haste, hexproof,
indestructible, lifelink, menace, reach, skulk,
trample, and vigilance.
{1}{r}: Other creatures you control get +1/+0.
