Victini: If you have 0 cards in your Deck during your Draw Phase, you lose. "Dual" should be "Duel."
Toxic: Tokens are fine, but counters would be better.
Mienshao: Should be Beast-Warrior
Garbodor: Should be Fiend or Machine, possibly Fish or Plant
Blissey: Wow. A tribute for 0/0? Blissey should have some serious DEF, and maybe ATK. At least 3000 DEF, in my opinion.
Ampharos: I'd make it a LIGHT monster.
Breloom: Plant-type. It's effect... Do you get to attack during the Draw, Standby, Main1, Battle, Damage, Main2, AND End Phase, or just one? And the attack block? It's kinda... powerful.
Mewtwo: Divine Attribute should only be for Divine types. Did you mean DARK?
Reuniclus: Instead of Aqua / Spellcaster, make it an Aqua and put in its effect that its also a Spellcaster.
Shedinja: Personally, I'd make it a Zombie type.
Latios: Why Water? And with only 1 tribute, its too easy to get it to 3500 ATK. And you should put "base ATK"
I hope this helps!
Victini: The idea is that you get to summon it before you lose the duel due to not having any cards. I'll word it differently if that's not clear.
Toxic: Can I put counters on empty Monster Card Zones? I figured I couldn't which is why I used tokens.
Mienshao: Fixed; will update main post when I can be arsed to.
Garbodor: I was unsure on what type to make my Garbodor, but Machine sounds right. Thanks!
Blissey: Eh. I feel like the effect kind of makes up for the low stats. Although, it's kind of hard to make your opponent attack a face-down DEF position monster that you just payed a tribute for, so maybe I should add some decent stats for Blissey to fall back on.
Ampharos: Maybe. It's already a Thunder-Type, so I don't see why it really needs
to be LIGHT.
Breloom: I meant for Breloom to attack one time during your Opponent's turn, but also be able to attack during any phase of your opponent's turn (i.e. being able to attack during main phase). Honestly, though, I don't really know how to word it. I'll mess with it a bit. Of course, if you could help, I'd appreciate it. Oh yeah, and the attack block is only for Breloom itself, so it can't attack during your
battle phase. I thought that was...clear enough? .3.
Mewtwo: I figured Divine would kinda fit. Mewtwo wasn't really evil or anything; he was created by some evil corporation that was trying to control him, and he got angry about it. If there really is something wrong with having him as DIVINE, I could change him to EARTH, maybe?
Shedinja: Hurrrrr. You're absolutely right. I'll change it.
Latios: From what I gathered, Latias and Latios are pretty well versed in traveling both the sky and the water, so either one would work. I just picked WATER for Latios because Latias was WIND. I guess there really isn't a point and I could change Latios to WIND. Or I could change both to LIGHT, or something like that. Also, since Latias also requires 1 tribute, and since they need each other to work, they still require 2 Tributes for Latios to have 3500 ATK. And since you can only summon 1 monster per turn (assuming I actually remember how to play this game), it will leave one of them vulnerable until you can get the other one out due to the low ATK/DEF they have for level 5 monsters. That was my idea behind balancing them, but something tells me that doesn't work, yes?
Well, thank ya' kindly for helping me with this stuff. This board is really slow, so I appreciate it. :<
