{R/G} Kamigawa Chai Tea (Persist Combo + Transforming Sideboard) (Modern) [Revision 1]

Modern Legal Red/Green Persist Combo Deck.

In Game 1, this is strictly a Persist Combo deck. Get any creature with the persist keyword on the field. Use Rhythm of the Wild or Melira, Sylvok Outcast to prevent the -1/-1 counters and allow you to recur any persist creatures. Sacrifice the persist creatures with either Goblin Bombardment for full damage or Altar of Dementia or full mill. Birds of Paradise and Ignoble Hierarch are turn 1 mana ramp that help you combo off faster.

Turn 1: Any green land, play Hierarch or Bird.
Turn 2: Any land, tap 3 mana for Rhythm of the Wild or Melira, Sylvok Outcast (Rhythm is objectively better because it appears less threatening without creatures on the field and enchantments are harder to kill than creatures.)
Turn 3: Any land, pay 2 for either Safehold Elite or Lesser Masticore, then pay 2 for either Goblin Bombardment or Altar of Dementia. Kill with damage or kill with mill.

In Game 2, you can transform this deck into an aggro deck that is hard to counter. Replace 4 Altar of Dementia with 4 Prowling Serpopards and 3 Murderous Redcap with 3 Greater Gargadon. With the Prowling Serpopard and Rhythm of the Wild, you have a total of 8 cards that literally say "Creature spells you control cannot be countered." You can suspend Greater Gargadon and use it as a sacrifice outlet on the turn you play it to get a 9/7 creature with haste for one red mana that cannot be countered if you have Prowling Serpopard or Rhythm of the Wild, and can be a 10/8 with haste if you have Rhythm of the Wild. Melira, Sylvok Outcast and your persist creatures are all going to be used to go wide. Can still combo off with Goblin Bombardment if able/necessary.

For sideboard, I have a playset of Damping Sphere because Tron players and Storm players hurt me and my family when I was a child, and Reclamation Sage is enchantment/artifact removal on a decent body so that seems cool. I'm not great at sideboarding though so the other 8 cards not used in the transformation are up to you.
