one piece op 07 booster box Bandai Japanese Pack 500 Years in the Future (OP07) This package includes many ways to strengthen leaders from previous sets One Piece Card Game: OP-07

This is on my short list of things to work on once the metagame becomes defined

Reanimators: Anathemancer, Bloodsoaked Champion, Corpse Connoisseur, Hellspark Elemental, Hells Thunder, Mikaeus, the Unhallowed, Murderous Redcap, Puppeteer Clique, Rotting Rats, Scourge Devil Persist is really strong here, since Olivia can negate the -1/-1 counter those creatures get after dying

I think if you want to use Manabarbs maybe you should look at more Artifact type ramp that won't trigger it

The Speed Demons (Dimir) Colors: Blue/Black Strategy: Artifact Bleed Key Cards: Winter, Cursed Rider / The Speed Demon / The Last Ride Like many of MTG Aetherdrifts Limited archetypes, The Speed Demons rely on Artifacts and have a plethora of Vehicles at their disposal
