The plan is to end up on Unchained abomination + Evil twin challenge to bring back your Evil twin link from the GY and pop cards during your oppenent's turn along with a couple of handtraps to slow the game.
The big Evil Twins monster is in the side deck in case you want to play it but I never felt like the deck needed it. It's not a good boss monster.
Bagooska and Saros are nice techs that are both fiends and thus don't conflict with the restriction of the link-2.
Overall it's a pretty fun deck that can somewhat compete with the meta on a low rogue level. Have fun.
