The theme is alright. But I think it could be better if the cards have something specific as a theme because they dont seem to work together. Ex: (counters, swarming, protection, etc. )

I only dislike these to cards because I found them unbalanced. The first one works like card trooper and it has stats really high considering its effect . Maybe if you lower the attack, it would be more balanced.

For the second, I think its stats are high. Maybe having an attack of 1500 would be better, It could be me, but I think you should low its attack.

And I have a question about this card:

Does it means once per turn, per duel, per what?

Ele-Beast is like Ameba with it's effect.

These cards were made long ago, so Bat was made before Card Trooper came out. So it shouldn't be judged against it.

What I meant was that the effect of bat combined with its strenght, and searchability makes it a too good card. Combined with cards like Reckless Summon and it woud become a increadible card.
