John Hancock

Whenever this creature gains a keyword effect, you may have another target creature gain that keyword effect as long as this creature has it. (i.e. if John Hancock gains haste until end of turn, target creature may have it until end of turn as well, or if he gains vigilance from an enchantment, target gains it as long as the enchantment is on John Hancock.)
{b}{r}: Flip a coin, if heads, this creature gains a keyword effect of your choice the end of turn, if tails, destroy this creature.
