Talisman of Assertion: I decided to remove the cantrip ability, to prevent the kind of abuse you were talking about. However, I felt that I could safely price it at 0 as a result of that, because unless its ability is used and can be used, it just sits there. There is in fact no card called Dense Canopy (as far as my searches indicated). There is a Dense Foliage, but no Dense Canopy. If I find a better name, though, I will change it. But I did change the price to GG - the only times when this card would be useful (most likely) are in Limited, and GG is probably a fair price for such an effect (which pretty much only helps on attacking anyway). 4-color hosers: That could work, but they would have to be a lot more powerful than the card you just suggested. That's basically just an instant Boil + a few damage for BRGW instead of 3R. This could be the blue-hoser, for instance: ~ BRGW Enchantment Whenever a player plays a blue spell, destroy target island. Blue spells cost 3 more to play. Spells that target ~ while it is on the stack cost UU more. Remember, these cards only work 1/5 of the time.
