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 'tap'.)

Sacrifice a land: untap Mawumag Fetish, it
gains hexproof until end of turn.
