Different Combo requirements: Genex Undine, Penguin Champion + any monster (level 2- 4) or Royal Penguins Garden + any card.
Most common combo: Genex Undine -> add Genex Controller + send Crystron Rosenix to gy -> summon token of Rosenix -> Summon Link Spider -> Summon Genex Controller -> Summon Crystron Halqifibrax with Link Spider and Genex Controller -> Summon Ash blossom -> Summon Penguin Brave -> Summon Penguin Solider / Penguin Ninja -> Done
Tech choices: I use Moray of Greed and upstart goblin to thin my deck, and if I am able to do, I try to get Crystron Rosenix and Nopenguin in the grave, since they give me free bodies. Nopenguin does multiple things, it keep summoning itself, chainblocks on Brave Penguin and makes Penguin Ninja and Penguin Soldier into "banish 2" for spells/traps and monsters respectibly. I also added a small torrential package that is simply effective in any water control deck.
I used the TCG banlist and the new Penguin cards to make this deck.
