Ojama Yellow

commonly used as well. partly because theyre so cheap to build (sea stealth attack or archfiend decks are overall more powerful but also much more expensive atm), and partly because multiple have made it to king of games already. theyre actually pretty neat, though I havent used them yet.

I know a bit about Alien (played them a bit on an older DS game) and I kinda like how they serve as a control and beat down based deck

its basically all they do, but they do it damn well. alien counters are pretty strong atm and aliens can do all sorts of neat things with them. theyre also pretty much the only deck to be able to run only archetype-specific backrow. luckily nearly all their cards, barring like one of their quick-play spells, are really easy to get due to their low rarity.
