(No dlc) Yellow Event
I used blue jump and yellow event to hit godrank this season. I've tried all the dlc-less decks but blue jump and yellow event were the most consistent.
So here is my list and guide
For the starting hand, you would want to keep oradrim fanatic, ranger. Keep shaytan demon only if you have khalim's training with you.
The reason for not keeping shaytan demon - 3 cost 5/4 is decent, but he will deal 2dmg to your face every turn. So he is not ideal for a collector.
General game plan - you have to avoid the enemy's lands and build yours the opposite way.
First, build a desert in front of your orb. See how the opponent responds. And then you choose your side. You build 3 deserts in a row most of the time. And after that, +1 or draw all the time.
The main thing you should know is the fact that you can double collect the wells - super early while the opponent can't. It's because you have oradrim fanatic and khalim's training.
You have to get values out of your wells, abuse them till they start crying, and then also get value out of their tear.
Anyways, after you set up your double collection, you need to see if you can deny the opponent's collection. Utilize your spells or movements - with oradrim fanatic, training, and flash wind, you have insane amount of mobility.
Towards the end of the game, you would want to use your cheap colossus to finish the game off. You can also rush the opponent with shaytan demon and manta rider ( just drop them between the well and the face) and the opponent will start panicking.
This deck has a 50/50 against most of the decks, so i think it is ideal for climbing ladder.
Small tip - buff your ranger against red/yellow decks because they have 2dmg removals such as soul drain and seifer's wrath.
