Having the lower level Horus monsters special summon their stronger versions through their own effects. This might be kind of slow since you need to destroy a monster your opponent controls with your Horus, then wait till the end phase to special summon it's next form.
Horus the Black Flame Dragon LV4 and Horus the Black Flame Dragon LV6 needs to destroy an opponent's monster before they can level up during the end phase. Mirror Wall can help you a lot, activate it when your opponent declares attack on your attack position Horus, then during the next end phase you can special summon the upgraded version of your current Horus. Use Floodgate Trap Hole when your opponent summons a powerful monster, it will then be stuck in face-down defense position unless an effect changes it's position. This provides an excellent opportunity for your Horus to get a free kill.
Actually, I'm running 2 lvl 8's and 3 lvl 6's in my deck. Also with the Kidmodos. It works decent. I suggest to keep metalmorph. It's great for when you have to beat ancient rules BEWD decks, REZD,.. also keep in the chalice. Neat card with a lot of potential. I would replace the WoDs. Or at least one for lvl up. You'll lack speed otherwise. Soul exchange is another tech, just for backup.
This deck is so hyped, but it is not so good as all people think... if you play against a control deck you fucked up, if you play against a mill deck, same... and if you play against a phoenix deck an he uses beatdown skill you also fucked up... tried it many times... its possible to plat 1 or max plat 5, but there is the end of possibilities :/
"Even with an effect that ignores the Summoning conditions, Nomi and Special Summon-only monsters cannot be Special Summoned from the Graveyard or if banished unless they have first been properly Special Summoned."
