Argostars Exosister

Okay hear me out... The synergy is that the Exosister XYZ monsters are warriors which gain battle/card destruction protection and that any two level 4 monsters can move into Exosisters. Also Argostars can play on the opponents turn and don't have to special summon during your turn.

Combo 1: Start with Argostars - Glorious Adra and either of Exosister Pax , Exosister Returnia or Exosister Vadis .

- Normal Argostars - Glorious Adra , banish to place Argostars - Lightning Tydeu and Argostars - Swift Capane . Use Argostars - Lightning Tydeu  to discard a card and special, search Argostars - Slayer Eteo . Special Argostars - Swift Capane  and xyz into Exosister Mikailis . Use Exosister Mikailis to search either Exosister Returnia or Exosister Vadis . (Use Exosister Pax to find the missing peice). Set Argostars - Slayer Eteo and activate turn 2. Notice how this is 4 summons and plays under Nibiru, the Primal Being .

This leaves you with at least 1 banish from Exosister Returnia and a bounce to hand from Argostars - Slayer Eteo (remember to return to S&P zone). Also Exosister Mikailis is now protected from effect destruction by Argostars - Slayer Eteo . If you predict they will move out of graveyard, chain Exosister Vadis to special up to another Exosister Mikailis and Exosister Gibrine / Exosister Kaspitell (for an additional banish, negate/lock out of graveyard effects). Exosister Returnia now would give 2 banishes. Since this is a 3 card combo, hopefully you have 2 handtraps still. 

Combo 2: Start with Exosister Martha and Argostars - Glorious Adra .

Normal Argostars - Glorious Adra and banish to place Argostars - Slayer Eteo and Argostars - Swift Capane . If this is impermed or effect veilered, you can still send Argostars - Glorious Adra to banishment for cost, but the effect won't activate. Then special Exosister Martha and special Exosister Elis from deck, xyz into Exosister Mikailis and search Exosister Vadis / Exosister Returnia (note that Exosister Vadis probably will not work under Dimension Shifter . Don't be greedy and special Exosister Elis  if its in your hand, you can get Nibiru, the Primal Being .

Your end board composes of whatever benefit you get from Exosister Vadis / Exosister Returnia , and bounce to hand from Argostars - Slayer Eteo and battle and card destruction immunity on your xyz monsters.

Combo 3: Only Argostars - Glorious Adra 

Normal and banish, place Argostars - Slayer Eteo and Argostars - Lightning Tydeu . Discard for Argostars - Lightning Tydeu and add Argostars - Home Stadium . Activate it and end turn.

In you opponents turn, you can face up negate 2 card and bounce 1. It's not much but its something (plus you will have 3 extra hand traps waiting)

Combo 4: Only Exosisters ( Exosister Pax , Exosister Martha , Exosister Elis ).

If you can push further, use Exosister Kaspitell first to get materials for xyz summon of Exosister Mikailis ,then  Exosisters Magnifica . If possible, search Exosister Returnia , if not, end on Exosister Mikailis and Exosister Vadis . If all goes well, you have 4 banishes on your opponents turn for them to deal with. 

If you get ashed, impermed, effect veilered etc... your plays stop dead. This is 7 summons so you can get Nibiru, the Primal Being . No battle or card protection turn 2. Would avoid unless you have crossout/called by in hand, and even then this is a low priority.

Pros and Cons:

Its not much but pros: 

- Can play with dimension shifter

- Small engine (s), can run 20 handtraps/going second cards.

- Only 4 summons, so plays under nib.

- Exosisters can OTK turn 3.

- Argonauts burn for time.

- Budget

- If Exosisters or Argonauts get support, might synergise even better IDK.

cons: 

- Very weak end board.

- No turn 2 plays.

- Argonauts destroyed by spell/trap and monster destruction.
