Welcome back to the Knowledge Pool. This week we have a Bronze scenario, so everyone should submit their answers to our google form.

Abagail is playing in a sealed PPTQ. She sits down for game 1 of her match, grabs a pile of roughly 40 sleeved cards out of her deck box, shuffles, and presents to her opponent. Upon drawing her opening hand, she immediately calls a judge and explains that this is her sideboard. She has several other sets of cards sleeved for quick sideboarding, and she just grabbed the wrong pile from her deck box.

Thanks for all the responses this week. Our highlighted answer is from Harm Tacoma, an L1 from Rotterdam, Netherlands.

So what we have here is a deck problem. Having sideboard cards in your deck for game one perfectly fits here.

So is it a warning or will we upgrade? It was discovered by the player so upgrade path 1 and 2 do not apply. We do not have to check for the third path either because no game actions were taken yet. We stick with giving out a warning.

As for fixing the situation: we start by fixing the deck. Abagail can grab the mainboard, check it and use that. Since the error was discovered during opening hands we force a mulligan. Abagail can shuffle the correct mainboard, draw a hand of six cards and proceed making mulligan decisions from there.

Harm covered all the things I wanted to touch, so I'll leave it at that.
