Once we get hold of some white mana, pay one of that (along with some more spare colorless) to activate the ability, targeting Cateran Overlord (in nontoken form, as always--actually, this ability can't target a token even if you want it to)
1) Berserk Recently unrestricted in Type 1, many a player has the story of how a friend of a friend died to a double Blood Lusted, triple Giant Growthed, Berserked Forked Scryb Sprites
While the banned list in Modern is long compared to that of most formats, it's not that long, and the number of cards that could potentially be unbanned and would also be expensive and hyped enough to sell a Masters set is very small (it actually might just be Jace, the Mind Sculptor)
However, if it somehow already had three landmark counters on it before it left the battlefield, you'll create three Treasure tokens
Amnesia is also a bit more expensive than youd usually see for a discard card, but I still think it works pretty well in blue decks
