Should Cavalcade of Calamity have pushed something else down into my Honorable Mentions despite my contention that 1/1 tokens isn't a very Gruul strategy
When Terra, Magical Adept enters the battlefield, it triggers, causing you to mill five cards and return up to one enchantment card from among them from your graveyard to your hand
Legendary Creature - Dragon Color tag templates(None) Liesa, Forgotten Archangel Flying, lifelink Whenever another nontoken creature you control dies, return that card to its owner's hand at the beginning of the next end step
I think even a single target Replenish would put serious constraints on the format and the types of designs WotC could safely make
Outside of token and squirrel decks, this is probably the weakest mode, but with synergies it can be just as strong as the others depending on the payoffs
