latest one piece booster box Two Legends Both new and classic members of the Seven Warlords One Piece Card Game OP-16

More commonly, you see Overlord of the Balemurk in Pioneers Mardu Greasefang, which does a rather stellar job of throwing key cards such as Parhelion II and Skysovereign, Consul Flagship into the graveyard that can re-enter play with Greasefang, Okiba Bosss trigger at the beginning of combat

It also burns for a good reason, making players think about playing a land or taking damage, potentially leaving them behind on mana

Being able to stack your hand with your best equip options and then boost all your creatures as a side-effect of stacking them on Kellen makes this card an auto-include for any red/white deck with an equip focus

And yes Im beating the comments, I know its a boring combo

That said, looking deeper at mana sinks can help you find some interesting options

Each booster contains 15 Magic: The Gathering cards and 1 Traditional Foil double-sided token, with a combination of 714 cards of rarity Rare or higher and up to 7 Uncommon, up to 5 Common, and 1 Land cards
