The latest iteration after hundreds of games with blurple and a climb to champion with it. A flexible midrange shell with many budget options. Generally the gameplan is to take control of the board early and leverage it to quickly pressure down the enemy. Usually you are trading turns 1-4, then switch to pushing face damage until you can finish with Horn or other top end around turns 5-7. Watch out for Misanthropia, which can totally ruin your day by smashing your board right before you start going after their face- Mind Freak is your friend. Adjust your gameplan to the matchup- you may play defensively against aggressive RO or valkyrie lists, or attack early against YG control or Fires of Creation decks.
Many of the slots are general- daigoju, black hatter, odinthrone, and loki's veil can all be swapped freely depending on your needs and resources. Just remember that you need to keep at least 10 enchantments for rainbow's end!
