DEF/800
EFFECT: During your opponent's Main Phase, you can Synchro Summon using this card you control as Synchro Material Monster.

i'm not really impressed, i guess it's an ok effect

Mono Synchron
DARK
Machine
Tuner
LEVEL 1
ATK/0
DEF/0
EFFECTS: If this card is used as Synchro Material Monster, the other Synchro Material Monster must be a Level 4 or lower Warrior- or Machine-Type Monster, and that Monster has its Level treated as 1.

I guess i could be good if, just if they made formula synchron unlimited or semi-limited

Bahamut Shark
WATER
Sea-Serpent
Xyz
Effect
Rank 4
ATK/2600
DEF/1900
2 x Level 4 WATER Monster
Effect: Once per turn, you can activate this effect by removing 1 Xyz Material from this card and selecting 1 WATER Rank 3 or lower Xyz Monster in your Extra Deck. Special Summon it. During the turn you activated this effect, this card cannot attack.

well right now its not broken because what it get get is useless without any any material on it what you can get is Leviathan dragon, acid golemn, areo shark, and wind-up carrier... this is how i see it play right now

me:now i special summon bahamut shark, now i use his effect to special summon number 30 acid golemn of destruction
opponent: HAHA noob now you'll just get burned the whole duel
me: now i activate creature swap
opponent: fuuuuuuu

but yeah if levi or acid golemn gets a chaos number like utopia then this card could get a little ridiculous.
note: bahamut sharks effect is not confirmed, but i'm sure hes not gonna get his effect changed.

so what do you guys think

bahamut shark........ hmmmm creature swap acid golem is basically a much better lava golem
cant attack and 2000 damage instead of 1000 also bahamut shark + that number 9 canopy star dyson sphere thing then it would be a broken combo. since if dyson is attacked with no xyz material u can put 2 monsters from grave as a xyz material and then the attack is negated
and then canopy star dyson sphear second eff is just broken.
hmmm mono synchron is good for formula and steam synchron is basically a lv 3 formula thats not a synchro

that probably the biggest reason it's rank 3 or lower water monster, to prevent the brokeness it could be but i think there will be more water xyz in abyss rising so that card still has something to look forward to. as for mono synchron the fact that it has to be a warrior or machine type monster bugs me a little but meh.

Those synchron monsters are asking for new 5D's season! :3

lol ageha mono synchron and steam synchron are already used in 5Ds

*editing ma synhcron deck* I wish they unlimit formula.. since fishborg/plants are dead.. i think they have no reason to limit

no reason except promotion of xyz (damn konami >.>)

Well, I do enjoy the concepts of the xyz, and the first card. The first card allows you to conserve yourself to make plays during your opt turn that could also ruin their play, but the xyz is pretty well made, for you can get game if you play with it properly.
For the level one mono synchron, I don't necesarily enjoy it since i would be playing other cards instead if i wanted formula out that badly.
