Ill bet theres a few cards youd have on your lists that maybe no one else would
Several factors influence Fusion Strike card values: card condition (mint cards worth 3-5x more), rarity (holographic and rare cards command higher prices), first edition status, PSA/BGS grading scores, and market demand for specific Pokemon
If the permanent card's mana value is greater than the number of permanent cards in your graveyard at that time, Squirming Emergence won't resolve
Pokemon has been doing a good job of featuring cards people actually want in their Hyper Rare forms, making them especially fun to collect in order to include in a blinged-out deck
They don't copy whether that permanent is tapped or untapped, whether it has any counters on it or Auras attached to it, or any non-copy effects that have changed its power, toughness, types, color, and so on
