Mawumag Fetish

{1},{t}: Put a -1/-1 counter on target creature, it gains cathode until end of turn
(If a source would subtract from that creature's power or toughness, it adds instead. If the text of
a spell or ability targeting that creature includes
the word 'destroy' change it to 'regenerate'.)
Sacrifice a land: untap Mawumag Fetish, it gains hexproof until end of turn.
