If you decide to not play the spell, the card goes from exile into your graveyard
The 226 different cards on offer right now are cannily oriented towards the peak millennial nostalgia years of Pokmon in the early 00s
Means now its 6:2:1, and given the number we have at each rarity level, the pool you pull from for a MUL card is 15 mythics (1 of each), 60 rares, (2 of each), and 120 uncommons (6 of each)
Tivit, Seller of Secrets can do it just by connecting for damage once, and there are many alternatives with all the artifact generators running around these days
The deck does get blown out by mass artifact removal but that's the risk you take playing an artifact deck
I encourage you to comment what terrible cards youve discovered yourself or seen players use at your LGS, or come talk about it over in the official Draftsim Discord
