The full combo:
Turn X: play your Strenght in Numbers (not needed every time)
OTK TURN: step 1: Play Forest Warden Omu and use Germination to get a new copy and refreshed mana crystals
step 2: Play Malygos/Kael’thas -> trigger Strenght in Numbers and get the other one from your deck
step 3: Play a cheap spell to refresh your mana crystals with (Germination) Omu
step 4: Play another Germination (free bcuz of Kael’thas) on Malygos
step 5: Moonfire/Swipe/Starfire with +10 Spell Damage
step 6: ——–> PROFIT
Ofcourse you can OTK without another Germination or without Kaelthas, the described combo is this deck’s full potential.
I decided to include Glowfly Swarm and Spell Druid cards so you can use Fungal Fortunes and draw the right cards.
This deck has a lot of options, like including EXOTIC MOUNTSELLER (since you practically have 9-10 0 cost spells), JEPETTO JOYBUZZ (to get your 1 mana maly and kaelthas) and stuff like Ysera Unleashed, Alexstrasza and Lorekeeper Polkelt, but I decided not to include (Battlecry) minions, so you can be more certain to get your combo minions with Strenght in Numbers (If you want you can drop Speaker Gidra, but it’s really good with Strenght in Numbers and Kael’thas bcuz it’s exactly 10 mana and a reaaaalllyyy strong minion with Starfire and stuff like that. Can always include a copies of Overflow or Crystal Power.
Hope you enjoy this combo, have fun 😉
