His envisioned tactics involved using [Treatment] for cards in need, and [Poisoning] for cards like [Double-Headed Captain], [Ghostfire-Youth], and [Little Ice Demon] that didn't rely much on health.
Another function could be to pressurize the health line.
[Mantis Lady], for example, is a card that needs to lower its own health slightly to function better.
It can be paired with [Spider Doctor].
It's worth mentioning that cards from the same Instance have a high degree of compatibility.
As for the other skill, [Bad Medicine and Good Medicine], it's a bit tricky.
If he predicted successfully, his team's card in the next round would still be subject to 50 points of [Poisoned].
It is essentially an attempt to extend the life of a card on the verge of death for one more round.
If the card's health is reduced to 0 and [Rescue] takes effect in the same round, [Treatment] will still be ineffective.
