Alright, this is getting ridiculous. I'm not even talking about the questionable switches in moods of the main character, seeing as he had a reason to be pissed at the humans (saint), while having no reason to really help them overall.
The inconsistencies however are ruining this bad.
First, life. Seriously, does life even MATTER in this story?! It did...for a single chapter...First one. He even said that the 1/1 elf going against the 2/1 naga would die while killing the naga. That goes in accordance with the game this is based on. However, a 9999/1 is AS EASY to kill as 2/1, and ANY elf should be able to kill that packed-up goblin. It have nothing special. No trample, so his attack shouldn't do jack squat to anyone but his target (certainly not rend hundredths of meters of earth). He doesn't have first strike, so he should have no means of preventing himself being killed with a single blow, either. But his 1 life suddenly doesn't matter...
Second, forest walk. What the hell is with that immortality?! In the very first chapter it appeared, the elf said that it requires both sides to be tied to a forest (in the actual game, both sides need a 'forest' land in play). But goblins are 'mountains'. Humans are 'plains'. They are fighting mountain monsters on plains. THERE IS NO FOREST THERE. Forest walk should not work. At all. It should be totally useless, as it doesn't mean anything that the elves have a forest some distance away!
Third, tokens. The goblin dude depends on goblins in the graveyard. Cool. Except, their method of generating goblins is...by creating tokens with the cook and one other, I believe. Tokens...don't go to the graveyard. Never. They are removed from play. Basically, they disappear and don't count for ANYTHING. What does this mean?! This goblin dude should have maybe 15, max 20 attack. The amount of REAL goblins that he started with, ignoring all the tokens.
Seriously. The concept of this story is entertaining, but there's a limit to how ridiculous and inconsistent a story can be before even the best idea is just garbage. And I consider myself having a lot of tolerance for low-quality writing if the general concept is entertaining. But this story have inconsistency within several pages (like this forest walk) of each other, and it CONSTANTLY ignores the very concept of itself. The health stat is the most fundamental part of the card game and is what determines how MTG is played. This goblin dude, for example...he'd be crap without some way to avoid being blocked or attacked back (first strike, 'walk' skill, flying at the very least). But since his crap life is totally ignored here, there are several chapters of unnecessary drama...
