Most recently I've tried out Ring of Pain and the Demo by Winnie's Hole by the same developers.
Ring of Pain is a pretty interesting Dungeon Crawler. Aside from the standard increasing difficulty with your depth into the dungeon, each floor takes the form of a deck of cards you have to navigate through in order to collect items, currency, fight enemies... etc
The runs are short and fast, although the narrative is a bit lacking with the story feeling like a less interesting Brutal Orchestra. But it's pretty entertaining, not really a deck builder if your looking for a new deck building rogue-like to try out, the items are just more equipment of which you can only have one of each per equipment slot.
Their newer game Winnie's Hole, is an actual deck builder although I think it has a pretty interesting take on deck building with the inspiration the game takes from Tetris. Instead of playing cards from a hand, at the start of your turn your cards randomly place themselves onto your a segmented board which takes the form of a brain.
You can then play the cards on the Brain Board using a Tetris piece in your hand, although once you play a Tetris Piece you can't get it back until you empty your hand.
In between combat you have an exploration phase where you use the Tetris pieces available to you in order to explore a map where you collect experience pieces, extra blocks to add to your Tetris pieces, and event tiles.
I don't really get why it's themed after Winnie, but that was probably more eye catching then honestly themeing it as the Tetris Rogue-like deckbuilder it is.
