square enix card sleeves Sleeves: Final Fantasy- Bahamut (FFCSS-17) (100ct) sized cards from the Final Fantasy Card Sleeve Series by Square Enix Final Fantasy 7 Cloud Strife

Here's how the deck looks with the upgrades added: Also to pre-emptively address some comments: one direction that you can take the upgrades is to really lean into Sliver Gravemother's encore ability and turn the deck into a straight-up Encore deck -- Buried Alive and Entomb cards to put slivers into your graveyard, Convergence of Dominion and Zirda, the Dawnwaker to make encore cost less (though PSA Training Grounds doesn't work, I see people suggesting it but sorry no), Mondrak, Glory Dominus to double the encore tokens, Sundial of the Infinite to keep the encore tokens permanently -- that sounds sweet and all but you'd need to do a massive rework of this entire precon, turning it from a Go Wide Sliver Combat deck to Sliver Reanimator essentially

Ultima, Origin of Oblivion is another neat card in the main set

Its a cheap, aggressive creature that loves turning numbers into pure damage

Each single-player deck includes: (1) Deck of 60 cards, including 2 foil cards (11) Paper damage counters (1) Paper playmat (1) Paper tracker token (1) Game rules (1) Booster pack of 12 randomized cards
