You may cast Cacnea from your graveyard by
tapping a Desert in addition to paying its
mana cost.
Last strike, protection from monocolored-blue.
Ingest (Whenever this creature deals combat damage
to a player, that player exiles the top card of their
library)
Whenever a creature attacks or blocks Cacnea,
that creature gets -0/-1 until end of turn.
Cacnea has flanking as long as the defending
player this turn controls a Desert.
