(See original pre-banlist decklist here: https://ygoprodeck.com/deck/kashtira-327406)
EDIT 9/15: Rip Arise-Heart. I'm not making an updated Kashtira list after this banlist, I've been getting bored of this deck anyway. Time to find a new meta deck to stomp with.
Diablosis ban means that you no longer get to go full combo to banish 7 main deck and 1 extra deck, and limiting of Arise-Heart sucks, but deck is still very playable. Terraforming plus 3 Wraitsoth plus 3 Prosperity means you still have a good chance to find Unicorn to start your combos, and you can still certainly end on your Arise-Heart.
More comparisons to my previous decklist from stuff that got banhammered (see link above): Triple Tactics has been moved to Side Deck, replacing Dimension Shifters which are pushed to Main. Added another Lava Golem - it was working really well for this deck, especially in the mirror if an opponent ended on both Shangri-Ira and Arise-Heart. Extra deck replacements include a copy of Flare Metal and Dracossack.
All in all, the deck did not get hit as hard as I thought it would. I was shocked Unicorn was only Semi'd, and that Wraitsoth and Fenrir didn't even get touched. Looking forward to trying this in the new banlist season.
