Iymrith, Desert Doom Having a five-mana 5/5 that flies is extremely powerful in a limited setting
You can overload your opponent's interaction by casting all your plotted cards at once
The biggest issue that Kona, Rescue Beastie has in my mind is that it falls apart when you compare it to Kinnan, Bonder Prodigy
You usually only get two out of three of the possible outcomes, which isnt ideal
It adds consistency to it, especially in a Pikachu & Zekrom-GX deck that is low on searchers
