enchantment, costs 1 colorless, 1 blue, from Apocalypse
1 : Target creature is the creature type of your choice until end of turn
creature: legend, costs 5 colorless, 1 black, 1 red, from invasion
7 / 4, protection from legends
2 black: destroy target legend. it cannot be regenerated.
Another fairly easy combo, specially if your opponents come with a barrage of many saproling creatures. With unnatural selection, change the type of one of the creatures as legend, then destroy the remaining one with Tsabo Tavoc. Piece of cake!
