Sixty Thousand Legs, One Mind

[Hydra of Ages]

I've always found it odd that there are rather few ways that insect-types can actually swarm. You'd expect that would be a given, really.

[Zeppeli Gyro Supreme]

Recently, Insects have been given the "theme" of constantly being added to the player's hand. I guess it's sort of like the bugs are laying eggs which hatch into new bugs? I don't know. Anyways, onto the cards.

Hivemind Larvae - Maybe a bit too Archetype specific, but still looks like a very useful card.

Hivemind Drone - Worker - Not too sure if this could be overpowered or not, but since it's a very specific requirement I'll say no.

Hivemind Drone - Soldier - This card could be potentially abused, especially in multiples.

Hivemind Princess - Perhaps make its last effect once per turn, or a specific type of destruction?

Hivemind Drone - Collector - With all of its effects combined, I feel this is a bit overpowered. It can either be a giant beatstick that helps you swarm, or a draw engine.

Hivemind Drone - Guardian - Again, potential abuse, but seeing as if you wipes your field you would be left with an 800 ATK monster, I don't think this is much of a problem.


Neural Network - I'm not so sure about this card... Basically if you get 2 Summons a turn at no cost, and you wont take any battle damage either.. which alone are fine, but together can create a very powerful and very annoying combination.

Pheremone Network - Again, the two effects alone are useful, but together they make the card imbalanced.

Resource - Sounds like a good card, and very useful for the Archetype. Nothing much else to say, though.

Butterfly - Perhaps a bit too powerful for a level 4. I would change it to level 5, so at least you can't use it with those Tokens that you generate.

Mantis - Being able to be activated on either player's turn is a bit too much. Other than that, it looks alright.

Hornet - Very interesting effect. The wording is strange, but it sounds very cool.

Dragon - You can't Normal Summon a Synchro... Though I don't think that's a mechanical rule. And also, if you did he would have 0 ATK due to being a ? monster.

Overall, it seems like a very cool concept, and it would be awesome to see something like this in the TCG.
