On The Frontlines...

[The Dark Knight]

I couldn't think of any Synchros/Fusions for these (I did include some Tuners though) so if some of you guys want to come up with some, that'd be cool.

First impression: Pretty cool idea. A bit strange, but I haven't seen anything like them.

But after reading all of them, I feel that some of them are a little OP'd. General is pretty crazy. Sure you have to tribute 2 monsters, but your immediately going to replace them and clear out any immediate threats as soon as he hits the field. And then he's extremely hard to get off the field since he can't be removed from the field with his effect. Top it off with a 3000 atk. Rediculously OP'd.

Militant Advisor is also pretty OP'd in my opinion. You basically play Militant Tactician, remove it from play and you get an 1800 beatstick while adding a Frontline Soldier to your hand. It's a good combination, but I would and it's fine, but he should be Special Summoned from the hand, not deck.

Veteran has way too many ways to negate things. In all honesty, the effects are fine, but putting them all together makes it a little to crazy.

Overall, I like it, but I feel that you tried to put too many effects into your cards. They would be more balanced if you spread the effects out among more cards. Have one high leveled monster special summon monsters from your hand, and make another that can't be destroyed while there's another frontline soldier on the field. You can use those effects for synchros as well.

It's a good set with a good idea, it just needs some balancing.

Yes, general is OP'd to the extreme. But nice idea

[The Dark Knight]

Okay, I did my best to soften up General and Veteran. General should be much more exposed now and Veteran has lost his negation power, but gained a new one. I also altered the Militant Advisor/Tactician effects. Plus, I added a new Militant Tuner monster and 3 Synchros.
