Berserker Kombinen

As you cast this card, you may discard any number of other cards with the subtype "Kombinen" from your hand and pay {2}{u}{b}{r}. If you do, create a Green Viking Berserker creature token with hexproof and power and toughness X/X, where X is 3
times the number of cards discarded in this
way. If you don't, put 2 +1/+1 counters on target creature.
