mtg clavileno commander deck Magic: The Gathering The Lost Caverns of Ixalan Clavileño, First of the Blessed

Nasty good combo in all of the places

Dual-purpose cards serve multiple roles in your deck

Foil-stamped signature art card replaces art card in 10% of boosters.

At the very least, Celes allows Persist to trigger repeatedly since the -1/-1 counter will be counteracted

Some examples: Swords to Plowshares, Teferis Protection, Chaos Warp, Great Train Heist (or other Spree cards, you pay extra costs but can go wild), Akromas Will, Deflecting Swat, Wear/Tear, and my personal favorite, Reprieve

Its a great blocker, it can get things moving on its own, and ultimately itll sit there gaining you life while you mill everyone
