Depends on how the turns go but I don't think that would be the case. 

With Gnishak he needs the 2nd attack to decrease the bomb detonation time.

Here is how I see it going.

1. Gnishak places bombs.

2. If all land that is 8 debuffs that are going on champions.

4. At 50% you could say that 3 transfer to Panda. Putting 5 bombs on the panda. So you have 5 45% chances to counter attack. Unless you are really unlucky you are going to counter attack.

5. Panda should counter attack first? If so the bombs decrease by 1 to one turn. Bombs get passed to someone. 

6. Gnishak's 2nd turn triggers.

Gaius - Counts on sleep to blow up the bombs. Sleep doesn't affect panda.

1. Gaius places bombs. Puts everyone in sleep. (Provided that it doesn't get transfered to Panda). Usually here, Gaius would then take his turn that detonates all bombs but Panda gets to counter attack because once again Panda has 5 45% chances to counter attack. Probably more due to the sleep. 

2. Before Gaius can do that Panda wakes up and passes off the bombs with the counter attack. 

I was thinking the same but this hero is better than people are making him out to be.... His real power is in the passive. Basically he is bouncy ball for all debuffs that will go on his team. What you are going to want to do is put him in avenging gear at the back of your team. If you are fighting any boss or hero that throws on a ton of debuffs you are going to counter attack, throw all the debuffs onto the other tean, and your A1 is going to slow down the entire enemy team. 

In arena I think that we will make any go-first bomb teams obsolete. He is going to pull off 50% of the bombs and throw them right back onto the other team with a counter attack. Sure it doesn't bounce petrification but there is nothing in the description saying that it doesn't bounce hex. Sick of mythrala. This may be a fun answer. Block buffs, bounce. Sleep, bounce. Etc. 

And then with any boss that throws out a ton of debuffs such as poison, not only are you cleansing your team but also loading up the boss. So you are going to be able to load up a hydra head with poisons. With bommel you cannot do anything about the bombs but the decrease accuracy and speed will be highly useful. 

Having the decrease speed on the A1 and the remove debuffs on the passive is going to be really nice. He isn't going to have to be fully booked to be useful. Since you are using his counter attack you don't have to have a ton of speed on him either. 

Also another huge problem with this champ is the transferring of those poisons in Hydra. Who wants 10 poisons on a head when you'd much prefer Dec Speed, Hex, Block Buffs, etc. Poisons will just take up the debuff bar. 

This champ is extremely niche and definitely not worth a traditional fusion.  

I refer you back to my prior point. Don't discount his value. There are very few champs who place speed down on their A1, and even fewer who have added utility in other areas. And, for newer players as well as later-game ones, I would expect the rest of his kit will add quite a bit of value to a Hydra team.

This really is turning out to be one of the easiest fusions ever. Basically a free legendary. 

What makes this one so easy? Did you happen to have enough shards to get the epic from summon? And enough resources to easily level all the subfusion champs?

Yes and yes. The epic from the summon wasn't difficult to get at all which makes the whole thing way easier. The thresholds weren't all that high. I will have plenty of shards left over and potions. 

I think tis more just that you haven't done these type of fusions before. From my recollection, the milestones are the same as they've traditionally been.

The first one I really put my heart into was Emic and that one sucked. I am glad that they are more on this side of the difficulty scale. 

Karato is still the hardest one I've ever seen. That one was just brutal. Glad we've never seen one that bad since.

It's been a minute but didn't that one legitimately empty both of our accounts? I vaguely remember opening a LOT of mysteries during that Summon Rush. 

Ah yes. Karato. The one I missed because I decided it was worth waiting until the daily quest reset to summon three more champs from greens.
