mtg cards like keen sense Planar Chaos Magic the Gathering x1 you may draw a card. The 36 Best Card Selection

Insatiable Avarice This one-mana tutor/card draw spell costs one base, three to draw three and then lose three life and three total to Vampiric Tutor a card to the top of your library but no life loss base and five mana for both

And that hasnt ended, we just flavor stuff after planeswalkers (Jace's Erasure, Liliana's Specter, Chandra's Ignition) or still after legendary creatures (Ezuri's Predation, Daxos's Torment, Kalemne's Captain, Gisa's Bidding, Geralf's Masterpiece, Oona's Grace, etc)

If were willing to pay a higher upfront casting cost, we can start to discount and abuse some extremely powerful abilities Twinning Staff, Helvault, Orthion, Hero of Lavabrink, or Tower of Fortunes

It might be somewhat risky to use in 60-card formats like Pioneer and Standard, but Commander and MTG 's newest format, Oathbreaker, are a different story
