One-Star Galaxy

[bumpalumpa]

This is an archetype that's built upon the gimmick of everything being Level 1- even Extra Deck Monsters! The main idea is to amass a ton of Level 1 Monsters in your Graveyard to power up the two main Synchro Monsters, which can only be summoned by using the main Tuner's effect.

I like the idea of completely trolling the meta by toturing xyz monsters with level-affecting cards like gravity bind, level limit area b and hoshigeki, which would all work well here. You could also run these with slacker magician and xyz tribalrivals for a more defensive approach.

Bumpadyboo, want some more feedback

How can you synchro summon a level 1 synchro monster?

Hoshi the One-Star Genius: Level 1/FIRE Spellcaster/Tuner 50 ATK/650 DEF
Once per turn, you can reduce the Level of one face-up Level 2 or lower monster you control by 1 until the End Phase.

Hoshi's eff will not work the way you want it to. See the wording of the effect of Phantom King Hydride: http://yugioh.wikia.com/wiki/Phantom_King_Hydride When you Synchro Summon using this card as a Synchro Material Monster, you can use Tuner monsters as the other Synchro Material Monsters.

My suggestion is: When you Synchro Summon using this card as a Synchro Material Monster, you can have the level(s) of all Synchro Material non-Tuner monsters is not counted when you Synchro Summon.
