A Pokmon cannot evolve on the same turn it was played, and a Pokmon can only evolve once per turn, unless a specific card effect overrides these rules
You can only use 1 ""Infernoble Arms - Durendal"" effect per turn, and only once that turn
Due to the fact that it's a Continuous Spell, you can search and activate it on your next turn, so you have to straddle your opponent's turn, and it's difficult to defend even one turn in this era where speed is increasing and removal is rampant
Your copy, if its a permanent creature spell, also gains haste
Even when playing multiple colors, it can be in your best interest to center your deck primarily around one or two colors, and be a little bit less reliant on the rest
