watching yt vod:

i’ve experienced this being inconsistent as well … although now watching this in a vod instead of being in the moment of it and just confused, it seems like the rule is something like “is there a spell in hand at the start of the turn, if so discard a random spell” … so if you have 0 spells before any “add you your hand” triggers occur, it doesn’t discard those (perhaps to save goldenizer or one of the spellcraft spells from being wrongly discarded), but if you already have a spell in hand, it seems like stuff that was just added is not safe, and so you can still discard a card like goldenizer if you were holding any other spell going into the turn … imo, this needs to be ironed out and made so that either nothing is safe or spells that are being added at the start of the shop turn are immune to the discard … it is just weird and jarring in its current state
