You are forced to play a card matching game. You get 5 attempts to match cards. Any cards you match, you add to your deck, regardless of whether you want the card or not. The following cards will be available for matching:
The color of each colored card will be dependent on which character you are playing as.
A gremlin is madly shuffling cards on a table. This monster seems to be a harmless one. You approach him out of curiosity.
Gremlin:Twelve cards! Match them to keep them! Five tries, no do-overs.
Gremlin:Are you ready? Let's start!
You complete the gremlin's game and look up.'
If you don't want to add any cards to your deck, you can just pick the same 2 cards 5 times and not add any cards to your deck
However, you could pick 2 matching cards initially, though the odds of this are somewhat low.
Be wary of the Curses that the game offers. On Ascension 15+, the second pair of curses can be the same curse as the first pair, so be more careful when on high ascension levels, unless you seek curses.
The Rare card offered is most likely to be beneficial to your deck, so try to see which card it is to decide whether or not to match it.
