Thanon, Brazen Barbarian

Doublestrike
If a triggered ability, of a permanent you
control, causes you to roll a die, copy that ability.
You may choose new targets for that ability.
{2}{u}{r}{g}: Roll a D6: Creatures you control gain
+X/+0 and trample until the end of turn where
X is equal to the die roll. Use this ability only
up to twice per turn.
