1 Bear is enough, replace it with a second Algiedi.
I'm not sure about Safe Zone and Emptiness. Safe Zone is shit against Prophecy, which will probably be a popular matchup and while Emptiness is good against certain decks it sucks against others ( Fire Fist for example). Wouldn't recommend it in an undefined meta.
You are missing 3 Fiendish Chain, which is good against about any expected matchup.
You also need Exciton Knight and Ark Knight in your Extra.
The basic skeleton I would use is this:
Monsters: 18
3 Constellar Kaus
3 Constellar Algiedi
3 Constellar Pollux
3 Constellar Sheratan
3 Constellar Sombre
1 Thunder King Rai-Oh
1 Brotherhood of the Fire Fist - Bear
1 Honest
Spells: 11
3 Mystical Space Typhoon
3 Fire Formation - Tenki
2 Forbidden Lance
1 Reinforcement of the Army
1 Dark Hole
1 Book of Moon
Traps: 9
3 Fiendish Chain
2 Mirror Force
1 Solemn Warning
1 Compulsory Evacuation Device
1 Bottomless Trap Hole
1 Torrential Tribute
2 Tech Choices ( Star Cradle, third Lance, Seven Tools/Trap Stun/ Dust Tornado,etc.)
