Solar Surge is an essential spell for PVP, and it's nonsensical to lock it to only High-Ranked players. When a lower-ranked player is up against a higher-rank one, they are at an entirely arbitrary disadvantage that is completely unrelated to skill-level.
There is no reason I see not to allow this. Solar Surge is a far less complex spell than something like a Pierce Enchant, and it would put everyone on a more equal playing-field.
Yeah. Also, having solar surge makes pvp more enjoyable. If you pull an enchant and you don't want it, you have to wait to discard it. Whereas if you have a solar surge in your hand that you don't need, you can just discard it there and then. Allows for less deck fails and an overall more enjoyable experience. Good suggestion
