The bigger issue is that, as we talked about before, it's not just (or even primarily) Reserved List cards being counterfeited
Wakka's last ability checks at the moment it would trigger to see if a counter was put on Wakka this turn
In todays world with planeswalkers everywhere, the average converted mana cost of a spell you want to counter has gone up considerably
The restriction to artifacts isnt too bad since many artifacts pick up counters worth proliferatingfor example, anything with modular, Astral Cornucopia, and Everflowing Chalice
Consecrated Sphinx A bit like Faerie Mastermind, Consecrated Sphinx is more draw hate than card draw but it still gets you the cards
You can exile cards from the top of your library instead of paying life, and thats huge with cards like Bolas's Citadel or K'rrik, Son of Yawgmoth
