Probably what I'll be playing in Legacy once I finish my current project

4 Beseech the Mirror
4 Wishclaw Talisman
3 Dark Petition
1 Profane Tutor
1 Mastermind's Acquisition

1 Tendrils of Agony

4 Dark Ritual
4 Cabal Ritual
4 Lotus Petal
4 Chrome Mox
4 Lion's Eye Diamond
2 Mox Opal
1 Gaea's Will

4 Thoughtseize
3 Inquisition of Kozilek
3 Duress

4 Vault of Whispers
4 Urza's Saga
5 Swamp


If I can't count to 60 the difference gets made up in swamps

Beseech is clearly broken beyond all hope of repair. Demonic Tutor+casting the spell for free and it just incidentally gives you access to YawgWill. Dark Petition may get moved around since 5cmc doesn't work off Beseech, and Beseech doesn't work off only BBB. Very awkward tension, Infernal Tutor may work better. Wishclaw is a tutor that you can bargain with, if only Beseech was an instant so that you could bargain in response to the activation.
