For most cards with harmonize, the idea is to play them from your hand first , at which point they'll resolve and go to the graveyard
For me and many other players, Sol Ring is the 10th piece of power
It has tons of burn, counters, card drawing, and more
#4 - Lasting Fayth (Green) Next up is Zanarkand, Ancient MetropolisZanarkand, Ancient Metropolis, which as a green player I was hoping to be able to put higher
This card is also part of the Reserved List
For me, the tipping point is in the card type creatures are just much better than sorceries, adding the utility of attacking and blocking, paying sacrifice and convoke costs and everything else you need a body for in Magic
