If you like playing Limited formats like Draft, Play booster packs (while marked up a bit) are a good way to jam some games after building your deck on the fly
After Concealment, we have some classic Equipment pieces
You remove a counter to fire upon your own siege engine, and Gatta and Luzza turns that damage into a new counter instead
the latter is a noncreature spell that will stay relevant at all stages of the game
You can then use Pluto's ability again on turn three to cheat out a high-value four-cost card like Lucky, The 15th Puppy or Tinker Bell, Generous Fairy , or combine it with one of this deck's many three-cost characters to effectively play a one-cost location for free
Lore is good, but putting a card in the bin ready for Retrosphere to pluck back later is even better
