Creatures your opponents control enter the battlefield tapped.
Whenever you cast an enchantment
or aura spell, choose one:
• Buff: Target creature you control gets +2/+2 and Lifelink until end of turn.
• Debuff: Target creature an opponent controls gets -2/-2 and loses all abilities until end of turn.
{1}{b}, {t} : Gain control of target creature with power 3 or less until end of turn. It gains haste.
If an opponent loses life from a noncombat source, you may draw a card.
