To my knowledge, there is no Spell Practice hack for the other games, but honestly, I wouldn't have it any other way. Spell Practice is good for new players who are building their basic skill set, and good for those cards with a heavy, heavy "you're doomed if you don't have this pixel-memorized" reliance on tricks, which most occurs in Imperishable Night anyway. Other than that, I believe it's far more profitable to actually play through full stages rather than being able to skip right to the part you want to practice. If you focus only on the parts you "want" to practice, your skills for every other part of the stage will decay, and you'll be less likely to survive those sections without wasting lives or bombs when you decide to step it up into a full-game 1cc attempt.
