Yummy Cookie
Ancient
Upon pickup, Upgrade 4 cards.
On pickup it opens your deck and asks you to choose 4 cards that can be upgraded, then upgrades them. The choice is yours, not random, which sets it apart from Sand Castle's 6 random upgrades. The effect resolves once on pickup, so the relic cannot be traded. Its icon changes to match your character, which is purely cosmetic.

When to take Yummy Cookie
Take it from Tezcatara in Hive when four targeted upgrades matter more than a turn-1 Energy burst. Pick whichever cards change the most when upgraded.
