In cEDH, thats massive tempo, especially for combo decks that need to cast Doomsday, Ad Nauseam, or Necropotence ahead of schedule
Token Doublers A great majority of the creatures in this deck have ETB abilities, so keep an eye out for the number of triggers which will happen when one of these token doublers is on board, particularly if they are creatures such as Adrix and Nev, Twincasters and/or Mondrak, Glory Dominus, considering both can become tokens thanks to Brenard
Notably, that +1 ability could create a single bug token, but if the cards in your deck are all lined up just so (and you happen to be running a lot of insects) it could create an unstoppable horde - and super early in the game too
So while some decks might struggle to produce a big payoff from an X spell, green strategies are often well suited to produce lots of mana in a short amount of time, allowing cards like Invasion of Ikoria to suddenly apply pressure with whatever creature is going to be the best solution to a given situation
