Waifu's Ring

Waifu's Charm is a Common relic that adds +3 flat damage to every card associated with your chosen Waifu. Since Wished Waifu cards typically make up a significant portion of your deck, this is effectively a deck-wide damage boost for a specific card subset. The +3 bonus is applied per card play, so multi-hit Waifu cards and cheap Waifu attacks benefit the most, since the flat bonus represents a larger percentage increase on low-damage cards.

It pairs naturally with any strategy that focuses on Waifu-specific cards, and Cracked Hourglass lets you tutor the strongest Waifu attacks into your opening hand to maximize early damage. Star Map further enhances leveled Waifu cards by stacking additional damage and block on top. The relic has no downside, but its value depends entirely on how many Waifu cards are in your deck.

In decks that have moved away from Waifu cards toward other elements, the bonus applies to fewer cards. Priority: always pick if your deck has multiple Waifu cards; decent filler regardless since you always have at least some.
