MTPW - Jolu, the Gift-Giver

Jolu, the Gift-Giver feels like a good build-around promo. It has a unique (and in some niche cases, outright debilitating) effect, and decent stats for its cost. In the Expedition format, it's a Mandrake-destroyer. Most playable mandrakes are cheap, and the deck is built to chain ultimate triggers. So for this holiday season as my gift to you, I present you with the answer to Expedition Mandrakes.

Jolu, the Gift-Giver can remove threats from your opponent's side of the board before they become threatening. Steal their The Merriest Mandrake and give them a Passionate Stonehammer in return. Bonus points if it's already used up its berserk. Shoaldredger is completely nullified as a threat in this deck, because its cost will almost always be 1 or 0, meaning we can trade literally any of our units for a 7/6 beatstick.

Tavrod, Auric Financier does a bit to meddle with the Mandrake strategy as well. Some of the best mandrakes don't have square stats, so The Merriest Mandrake dies when Tavrod drops, Goliath Flytrap loses its staying power, and Shadowcreeper becomes a chump-blocker.

Jolu, the Gift-Giver doesn't really fit with the valkyries... or any tribe in the expedition format... but she does her job of disrupting the enemy's unit-based gameplan in just about any matchup.
