While were on the subject of unfair, I think Monologue Tax is more playable than most people think
It allows the player to draw two cards at the cost of discarding either an artifact or two cards

Thankfully, it also lets you really plan ahead by giving the top card of your library Plot equal to its mana cost (as long as its a nonland card) and allowing you to cast it with that Plot cost directly from the top of your deck
Bloodhill Bastion Plane - Equilor Whenever a creature enters, it gains double strike and haste until end of turn
Its a little expensive for what it does, but its flexible in the decks it slots into, be it planeswalkers, +1/+1 counters, -1/-1 counters, and so on
