Try this deck out. It is the best way to make use of Bajula as far as i know. Sure it lacks water, but it is quite brutal. I wins against rush 9/10 times, despite looking like a slow-start deck, as it can soulswap out Bombazar on turn 4. It also beats control decks, water based decks and other Bombazar decks very consistently, as it very easely summons Bajula way before they can use their 6 mana removal cards. It also usually summons Bombazar faster than regular Bombazar decks.
This is a TCG deck, despite all the japanese cards you see there. I just like to make the decks as holographic as possible. As you can see i also run a tech Scarlet Skyterror as well. This guy is usually always put in the mana zone, so that i can soulswap him out later against defensive decks. Bombazar is the true finisher of the deck, but Bajula is the reason it can win longer matches against those annoying control decks. Soulswap and Velyrika is what makes the deck consistent, as they make almost every card in the deck accessible at all times. With all the mana accel in the deck, you will often end up with a lot of good cards in your mana zone. But this is actually a very good thing when running 4 Soulswaps. Velyrika searches out Bajulas, Bombazars, Bazagazeal or just another Velyrika. Cocco Lupia makes everyting a lot more playable, and works extremely well with Jagalzor both early game and on that second Bombazar turn.
The deck also runs 16 shield triggers, which makes it matchup against rush and aggro even better. Once they start giving you those free Fairie Lifes and Dimension Gates, they are quickly burying their own grave, as they set you up for a Bombazar finish.
The deck is really iconic, and is extremely fun to play with, despite essentially being another Bombazar deck. It just is a lot cooler than the other standard Bombazar decks, even though it may not be equally overpowered.
