Here's a few decks which I'll cover in depth on(do PM me if there are more):
Tachikaze(Let's face it we all know it's the cheapest deck by far!): Tachikazes are a clan that was very unsupported when it came out in the early sets with it being release 4 cards 1 of each grades. But since BT03 came out Tachikaze received a big boost which made it one of the toughest decks. At first I hated Tachikaze and think it sucks. But after a few consideration I thought why not give this clan a try and I fell in love with it! Tachikazes are beast their main aim is to drop their opponent hand size through Raw Power therefore if you're those that love playing brute force play Tachikaze! If you think Tachikaze deck is slow behind the current meta think again Tachikaze could compete against the big three provided if you pilot them well. Tachikaze doesn't need that much strategy besides knowing what to call and what not they rely more on power over intellect!
Neo Nectar: Neo Nectars are another clan that is rather cheap to build. The only expensive think are probably Trailing Rose and Blossom Rain and glass beads
Alright so today I'll share a review of Tachikaze deck and here are some cards(Of course, that's my translation, this is a rough review so I'll name it "Building on a Budget Part 1(Edited):
Dragon Egg
Grade 0/Dinodragon/Power 4000/Guard 10000
Effect:
Auto[V]: When you ride a <
Auto[R]: (CounterBlast-1) When this card is sent to the drop zone, you may pay the cost. If you do, return this card back to your hand.
Which means this card is a really great card. A free 4K yes I know 4K is low but who cares its still a great booster. Even Battleraizers a great booster(even without an additional 3K but not many will run them) alright back to its effect, having able to return itself with a counterblast of 1 ensures a great 10000k to guard with. And on top of that Cannongear and Deathrex are able to boast about eating their own race. With a 19K power when boosting Deathrex it can ensure a 10K guard one-trigger-pass Attack, which if attacks hit makes you eat a unit since we all know T-Rex will go hungry again after battle. And Cannongear a 15K but it's useless of course against the current meta. Although I still bring it back to my Cannongear.
Now for the triggers, Tachikaze have currently 5 Different type of triggers which this deck kinda lacks. So here it is:
Black Cannon Tiger
Grade 0/High Beast/Power 4000/Guard 10000/Trigger: Critical, Power +5000
Auto[R]: When this unit boosts a unit and that attack hits, you may SoulCharge-1. If you do, return this card back to your deck and shuffle it afterwards.
So basically this card is a recyclable Critical Triggers which makes your chances of getting it again is great. As different Tachi builds have different chances, the replacement build thins out quick but is weak, the Raw Power build loses out in speed up on thinning but makes up for the High Power. There are many variants of these two build but of course there are mix but I consider it inconsistent. Back on the effects it's a sad 4000 Power unit so you can boost for a Free SoulCharge or simply use it as a 10k guard.
Savage Shaman
Grade 0/Human/Power 5000/Guard 10000/Trigger Heal, Power+5000
Just a normal Heal Trigger.
Herbivore Dragon, Brutesaurus
Grade 0/Dinodragon/Power 5000/Guard5000/Trigger Draw, Power+5000
Another Vanilla trigger. A drawTrigger I would play 4.
Pack Dragon, Tinyrex
Grade 0/Dinodragon/Power 5000/Guard 10000/Trigger Stand, Power+5000
It's the stand trigger for this deck. Vanilla card too.
Bombarding Dragon, Sledgeanklyo
Grade 0/Dinodragon/Power 4000/Guard 5000/Trigger Draw, Power+5000
Activate[R]: (Move this card into your soul) choose 1 Tachikaze Unit, it gains 3000 Power until end of turn
It's much better than Herbivore in much better ways so if you had this card play 4 instead of Herbivore. But it's PR which means from Promo Pack which currently There's no English Edition yet.
