Lets look at some others: Wickerbough Elder is maybe a little overcosted, but being able to put extra -1/-1 counters on it and turn them into a one-mana Naturalize should help shore us up against problematic artifacts and enchantments
At six mana, youre usually getting a hand refill with this in token decks, but leveraging that counter is where the brain starts to tick
Once per turn, when creatures with counters on them deal combat damage to a player, the player who controls Tidus can draw a card and proliferate (i.e., add an extra counter to creatures and permanents that already have them)
If you spend $199 or more, your order will include the rainbow foil Sol Ring Sweet Tooth card
Ive been trimming tutors from my decks lately, but clearly Worldy Tutor, Vampiric Tutor, Eladamris Call, Demonic Tutor and so forth can all boost your consistency in high powered pods
