i thought of an ok deck idea. i was gonna use reasoning and monster gate to get out lvl 7 and 8 mosters (or even lvl 6, im not sure) and use metamorphosis on them. with the new gatling dragon and the old warrior from another planet it would work. i could also get out king dragun but i think warrior from another planet is better. are there any other good lvl 7 or 8 fusions too? and are there any decent lvl 6 monsters and fusions? and one other thing, im not sure if i should make this deck like a beat down or what. any ideas would be well appreciated. thx in advance!

This type of deck is getting more and more popular. Some of the best high level monsters are those that have a decent attack with very good effects. These are monsters like:
Dark Magician of Chaos,
The Creator,
Guardian Angel Joan,
Mystical Knight of Jackel,
Tyrant Dragon,
Sacred Phoenix of Nephthys.
etc

Some good single tributes are:
Jinzo
Blowback Dragon
Dark Ruler Ha Des
Airknight Parshath
etc

If you are going to use metamorphosis then I suggest using more level 5 monsters than level 6 because most of the time you can morph them into better fusions, like Balter. Also Fusiler Dragon, the Duel Mode Beast would work well in this type of deck.

Level 7:

Fusilier Dragon the Dual Mode Beast
Mystical Knight of Jackal
Armed Dragon LV7
Guardian Angel Joan
Silent Swordsman LV7
The Last Warrior from Another Planet
Levia Dragon - Daedalus
Barrel Dragon


Level8:

The Sacred Phoenix of Nephthys
The Creator
Horus the Black Flame Dragon LV8
Black Luster Soldier - Envoy of the Beginning
Chaos Emperor Dragon - Envoy of the End

Dark Paladin

Good/Decent/ok (not necessarily the BEST) level 7 monster's (that AREN'T fusions and such)

Dark Magician
Swift Gaia the Fierce Knight
Buster Blader
Guardian Angel Joan
Fusilier Dragon the Dual Mode Beast
Red-Eyes B. Dragon

Sanga of the Thunder
Suijin

Same as above except Level 8's

Berserk Dragon
