Like most Magic: The Gathering cards, the value of Angelic Skirmisher depends on a few consistent factors: its rarity, the printing and finish (regular or foil), its physical condition, and the set it was printed in (Gatecrash)
The idea is to use this effect to put our opponent in a compromising position , which opens the door to several possibilities, such as Forcing them to retreat a Pokmon that has no Energy to attack or a high retreat cost, allowing us to attack and steal its Health for a long-term advantage
This is worth it as youre going for 3 high-power attacks that will likely win you the game or force tons of Counter resources from the opponent
Rebound is an effect that makes it so that you get to cast the spell again in your next upkeep for free
Knowing which sets have valuable chase cards helps you spot potential value
Rebound doesnt work with madness or suspend thanks to that important from hand clause
