one piece booster box odds TCG: OP-10 - ROYAL BLOOD This pack features many characters from the Whole Cake Island Arc One Piece Card Game Op05

Our main goal is to use Paradise Druid and Growth Spiral to get it on the battlefield as quickly as possible, which in turn will allow us to (hopefully) start playing Ultimatums for just one or two mana by cycling cards like Boon of the Wish-Giver and Migration Path

Emet-Selch, Unsundered Emet-Selch brings Yawgmoths Will, a card banned in Commander, to Standard legality

Powerful and evocative cards from across Magic history can also appear (sometimes featuring a borderless treatment as well)

That comes out to 2.5 mana per card, without accounting for the mana you spent on the sacrificed creature, which is pretty decent in the grand scheme of things
