Maybe make it an ETBF ability
All you need is these two cards and anything like Foundry Inspector that reduces the cost of artifacts
Cards with effects that are too small or too expensive, for example, Hissing Miasma only makes opponents lose 1 life, Hedron-Field Purists costs 15 mana to prevent 2 damage from each creature, Orim's Prayer only gains you 1 life per attacking creature, etc
If youre looking at a standard Pokmon card, check the left side about halfway down the card for a 1 printed in a black circle and the word EDITION directly above it
Given your focus on spell-slinging, youll usually have less to lose from this card than other players at the table
