Feel free to be creative when planning on how to cast your powerful spells earlier than your opponents expect
If you have 9 counters already from casting creature spells power 2 or less thanks to Ezuri, Claw of Progress being on the battlefield, you can cast Glistener Elf and itll become an instant threat because it comes in as 10/10 with infect
If you attack you gain life and if you smack your opponent around enough you can win by commander damage alone
This is a perfect choice for players who enjoy creature-based strategies, +1/+1 counter engines, Equipment value, Aura synergies, and aggressive Gruul gameplay
The card dips for now, although I can see Ashaya, Soul of the Wild creeping back up again if it manages to dodge a reprint for the next couple of years
Shadowborn Apostle is one of the more popular cards that does this, letting you play as many copies of it in your deck as you like
