After testing all spells,
I must say that each of them is pretty interesting and most of them are actually really cool. I decided not to look into the coding too much, as this is something for the judges

In order, I tested:
Kyrbi0:
I liked this spell because it is a passive summoning spell and it reminds me of actual maps years ago and because Kyrbi0 only had so little time and still submitted it. Obviously it has flaws, no need to elaborate that further in that context.
Chaosy:
THe creativity is awesome, as it is something outside the box yet still related to the topic. I personally thought, that the texttags were flying too quickly and that it was a bit unfinished - but I love cooking, so cooking units seemed great.
Almia:
I realized after testing all spells, that this is the only spell, that actually summons the primary unit of the spell at the target location, which makes it outstanding from the others. Its amazing how all these effects of the devourer do not cause any lag.
crabas_sakti:
Actually I did not understand, how that Ecto-Blast worked because sometimes it seemed to kill very distant units rather than close ones. To be honest, this spell did not thrill me too much, but it was quite fun to use the summonings as suicide bombers.
DD_LegionTN:
It took me a while, because the fact, that the sphere is in the air, is not visible at the beginning. It looks pretty cool, if you adjust the camera and I think that the impact of the sphere looks really great but there is too many summonings somehow...
Emperian:
I liked this spell a lot because you could combine the basic spell with acolytes - overall amazing because it looks good, works well and the concept relates to classic wc3 lore.
Flux:
Obviously, this spell is impressive as hell, I think there is nothing more to say. I would have stopped and simply voted for Flux but then I realized, that it is not a real summoning spell. I mean, of course, you summon a plane that summons goblins, but it did not feel like summoning something.
KILLCIDE:
I always am impressed by complex GUI-based spells. To be honest, the spell looked really good in KILLCIDE's description but it was hard to handle in game without getting in to it a bit. Iit is fun but a bit tricky to use. I thought, that this spell had the same problem as FLux's, it does not really feel like summoning something.
Loner-Magixxar:
Feels a bit like pokemon, and really nice concept. There is a lot of summoning, which is good, but I thought, that the different golems looked too similar - so it became very confusing in the end.
Meatmuffin:
It was really fun to try to hit as many enemies as possible with that sphere, and I actually liked and disliked - at the same time -the fact that summoned minions are not controllable. I really felt very undecided after testing this spell.
Rheiko:
In my opinion, the spell laked a bit in creativity, but it was performing well in game, and I think, also because it is GUI-coded, it can actually be useful for a lot of people creating fun maps.
Tank-Commander:
Tank-Commander's spell really amazed me from the beginning, because I liked the concept, creativity and basicly everything. The only flaw in my eyes was the realization of the overhead plague indicator.
xxdingo93xx:
I liked the idea a lot because it reminded me of Maplestory's shadow partners. Again the same problem - it does not feel like summoning something, despite having a huge shadow mate behind one's back. Still it is pretty awesome.
Decision:
I found it really hard to decide in the end. In the end, i tried to decide between Flux, Tank-Commander and Emperian, which I would consider a tie. In the end, I decided to vote for Emperian as 1st, Tank-Commander as 2nd, Flux as third. I would say, it is a tie though.
