mixedrandomj Wild Flame: All I see here is a logistics issue. You have to decide what creature is going to be hit for each individual point of damage. It's just....weird. I don't see this working nicely with even just two potential targets. It will just take too much time to resolve. The costing and rarity look right, but the card is just time consuming and potentially confusing to even experienced players for such a relatively minor effect. 6/10
Robe of Wards Artifact - Equipment As ~ enters the battlefield, choose a color. Prevent all damage from noncreature sources of the chosen color to the equipped creature. Equip
Understandable. I was thinking of letting it deal 3 damage to a random target originally, and it was an instant. I didn't like how it was a straight up chance of being completely bad or completely good though. Also you forgot to put anything for the scene so I am assuming this is an attempt to just defend from the crystal.
Magebane Armor actually does something similar to this, with a big buff to the creature as well. The protection is slightly different however, being a specific color source for anything but combat damage, that makes this a little less useful. I think this could have been equip or casting cost , without being a problem. Either that or a plus to toughness maybe, so 9/10.
The golem notices kaya don the protective robe, and points at the crystal. It's voice echos again. "Contain?".It seems to want help containing whatever this is.
The big crystal in the center's glow changes from red to green, causing plant life to sprout and take form as spiked vines which attempts to drag both up into the air and slash at them.
Thorn Lash Instant ~ deals 4 damage to target creature with flying, and 1 damage to each other creature with flying. They lose flying until end of turn. "Even the skies of forests are the territory of the wild"
