Is the card destoyed after 4 turns or does the effect loop?
The card will be destroyed of course.
As for decreasing quanta and time of effect, would you maybe recommend dropping it to 6 for unupped, for maybe 2 turns and do +3/+3 and 8 or upped for 3 turns with the same +3/+3? I just woke up so I'm confusing myself with the math right now lol.
My main thought on this was to implement it in a rush type of scenario, drop a few quick RoL's and then play this for some quick and heavy damage. Luciferase could even come in handy too now that I think about it, play a bunch of frogs then this card and watch your frogs grow.
