Beedrill

You may sacrifice a creature named Kakuna
rather than pay this spells mana cost.
Beedrill can't have -1/-1 counters placed on it.
Flying, double strike (This creature deals both first-strike and regular combat damage.)
Whenever Beedrill attacks or blocks, reveal the
top card of your library. If its a land or Berry
card, Beedrill gains infect until end of turn.
(This creature deals damage to creatures in the form
of -1/-1 counters and to players in the form of poison counters.)
