Streets of New Capenna has a lot of cards for every format and is less Standard focused than a lot of other recent sets which should give it a longer lifespan and cards that remain viable for a long time to come. I've always been an Ob Nixilis fan, so he was my first focus for a new deck. I've been running and working on fine-tuning this deck in Arena and it has been doing really well. Even without Ob, the Oni-Cult Anvils have won a lot of games. Sacrificing an Oni to an Oni generates two tokens and two ability procs. Ob is tough to deal with, and usually results in 2-3 for 1 to fully remove: 4 Ob Nixilis, the Adversary (SNC) 206
4 Mountain (SNC) 269
4 Swamp (SNC) 267
4 Voldaren Epicure (VOW) 182
4 Bloodtithe Harvester (VOW) 232
4 Oni-Cult Anvil (NEO) 230
4 Deadly Dispute (AFR) 94
2 Shambling Ghast (AFR) 119
4 Voltage Surge (NEO) 171
4 Body Dropper (SNC) 168
2 Tenacious Underdog (SNC) 97
3 Fell Stinger (VOW) 112
3 The Meathook Massacre (MID) 112
2 Hive of the Eye Tyrant (AFR) 258
4 Blightstep Pathway (KHM) 252
2 Den of the Bugbear (AFR) 254
4 Haunted Ridge (MID) 263
1 Sokenzan, Crucible of Defiance (NEO) 276
1 Takenuma, Abandoned Mire (NEO) 278
