River's Rebuke : This card only affects a single player, but it returns all nonland permanents that player controls to their hand
Much like Gavin, my favorite Final Fantasy game outside of the collaboration is Final Fantasy Tactics Advance
Nissa, Ascended Animist is fantastic in any format and deck that can manage the MV
They sadly only do 60 damage when built though, which makes the wait for them to appear, and to be built, not always worth it
A 3/4 legendary creature in Temur's Red, Green and Blue Mana colours, she can exile a legendary artefact or land from the controlling player's graveyard when she attacks and slap a discovery counter on it
Toxtricity will take 30 damage itself upon each use of this move, though this is arguably worth it net a prize card or two
