The creature we sacrifice at the end step is just a token from Grave Titan (triggering Eloise, Nephalia Sleuth), right
Id like to extend a big thank you to Lorcana Decks on X/Twitter for aiding in my decklist research and DreamBorn for their super easy to use deckbuilding tool
This Special Illustration Rare depicts Charizard bursting through a cracked obsidian backdrop, wings spread wide, flames roaring
Thalia and The Gitrog Monster offers a ton of disruptive value, plus card draw and a human horror frog commander that basically cant be interacted with in combat thanks to deathtouch and first strike
Still, its best to leave it in your Limited decks, where it's obviously very good
However, you can expect to pay somewhere in the neighborhood of $1,000 for this card, depending on the card's condition and the state of the Pokemon TCG market
