Hold down a bit, first you gotta see what a real garbage is to say that
Vaskii, Viper and GARDNA at 2x? seriously, max em out. Scylla, thats your personal choice, i wouldn't run more than 1 but i guess 2 is not that bad either. Now, Medusa, that is a garbage and needs to get out of that deck once for all.
Well those are not main problems, the main ones that concern me are:
Hand Destruction.... wtf.
Recurring Nightmare....wtf i mean cmon, either summon it immediately or don't return it to hand when you don't need to with searchers and other synergic things this deck can have.
Spirit barrier.... yea right. i cant comment this.
Snake whilstle..... just dont okay? :D
Just a question for curiosity, is offering semi limited or you just don't want that power in your deck randomly? lol
You need power. That means you need LADD. then you got more LV8 from which 3 (vaskii) are searchable with Gardna. Can you sense it, smell it in the air? yea, Trade In. Because of LADD and Vaskii use 2x Spawn. LADD will slow down your opponent and grant you more time to get what you need. Now I would even go and use Pot of Duality which you may disagree totally but you really need to see between the lines here. If you use Pot of Duality, that will give you many options what to draw and will increase drastically your deck consistency compared to Trade In for example for which you don't want to discard anything right? Now its obvious you can't special summon in that turn and you need to do something anyway to stay on course or you will get smashed. You got 6x defensive monsters there and you can have even more: Oshaleon. that little lizard will make your search even better. Now, Naga is okay alone, its effect is your key for Reptilianne Vaskii and Viper. Those two will be your bug eaters once Naga makes bugs from normal monsters lol. So, is there something more you can do while you cant special summon that turn u used PoD? ofc there is, Viper = 0atk, Naga = 0atk, Gardna = 0atk, Oshaleon<1500atk.... you get it? CREATURE SWAP. Max that thing out and annoy the hell out of your opponent. You can attack into your weak monsters, do so much damage with some good opponents monster you took, and + get your search. Of course search does not work with Gardna since you gotta control it to use its effect but thats not a big deal once you got one pro monster from your opponents lol.
On top of all, if you prefer or don't know how to use LADD properly you can even try Ananta. Simply remove any number of reptiles from grave (you need just one really lol) and end your turn to destroy opponents card. that is one more way to destroy things lol.
So we made plus here plus there plus everywhere to make this deck much more consistent and awesome and fun to play. Make the changes and enjoy
