Alright so first things first with all customs the question that needs to be asked is. "Why does Kuriboh need this if at all and what power level would be acceptable.

It seems your trying to make your field spell a catch-all that heavily improves kuriboh (which is a defensive archetype) into an aggressive beatdown strat that also has hand restock potential.

The first effect alone would be enough for the card, everything else seems like needless bloat, Not all powerful field effects need to float esp if they offer that much gas while up.

That said, If your running a kuriboh deck, half the fun of it is the fact that it isn't hyper oppressive, its just turtling as much hits as possible until it can turn the game around.

So I feel like the custom as is is unnecessary, for that reason alone if not for its unbalanced card design. To start you should skim it down alot and keep the core component of the card you want to keep.

That said I would like to see what type of 'kuriboh' deck your making before you try to slot in a field spell like this. 

But for now, I recommend just make the field spells effect be only the first effect.
