Knight's hand consists of Limit Break+, Power Through+, Entrench+, Body Slam+, Second Wind+, and 2 Wounds.

Relics seem to include Burning Blood, Bird-faced Urn, what I am assuming is Membership Card, Bag of Perception, Velvet Choker, Cultist Headpiece, Eternal Feather, Pen Nib, Tiny House, Gambling Chip, Clockwork Souvenir, and Torii. There's a few like the Magical Hat, the bottle, and the thing next to Eternal Feather I can't quite identify as corresponding to an ingame relic

Item left of Eternal Feather is Paper Phrog, and the item next to it is one of the Bottled items (fire, lightning, tornado) but I couldn't tell you which of the three, and I'm not sure what the item inside it is. Only item I can't identify is the magical hat. That one seems to just be a plain YGO reference, cause there's no similar relic in STS.

Thanks, Slay the Spire autists, your comments are very nice.

Annotated some of them.
I'm pretty sure the bottle beside Toadally Awesome is a YGO card, but I don't know its name.

The one on the left looks like a Myutant card
