The biggest problem is that your consistency card is also your best finisher and you can't use it as both within the same turn.
you need either Mikpolar + Mega + Slider or Mikpolar + any 3 Ursa monsters from this deck which we do play 15 of but that is probably not enough so you might need to increase the number of Ursarctic monsters you play because Mikpolar is just that bad without Diva
I tried making a new combo with this that leaves you with a hand at the end, its not great but it does leave you with a good turn 2 which is very midrange. NO 4 CARD COMBO IS GOOD and you get
Mega + Mikpolar + Slider + Diva (it is very unlikely such as Slider at 33% to open) no 4 card combo is ideal
- Activate Mikpolar, tributing the Mega, to SS Mikpolar
- On summon, Mikpolar effect activates to search Alpha
- SS Alpha and search Radiation
- Activate Radiation
- Activate Slider to SS the Mega in your GY
- Special Summon Polari, draw 1 due to the effect of Radiation (1)
- If you drew Diva, Normal Summon Diva, 1 Dipper counter
- SS Gurnards, 2 dipper counters
- Synchro Repetiteur, 3 dipper counters
- Repetiteur + Polari -> Coral Dragon (2), SS a mega
- Coral Dragon + a Lv7 Ursa -> Polar Star, draw 1 (2 from Radiation, 3 total), 4 dipper counters
- Polar Star + Big Dipper -> SS Septentrion w/ full ED skill drain (3 from Radiation, 4 total), 5 Dipper counters
