The Magistus Sisters

I'm a novice deck builder but this is the deck I've created after playing it for a while. This deck has 5 starter pieces that also play into one another whilst being and having decent exstenders giving this deck a lot of synergy, you are primarily going for Exosister boss monsters due to the restrictions from martha and vadis however there are times when you do need magistus monsters, as each magistus monster can steal, negate, or destroy Extra Deck Monsters and spell/trap cards. The magistus boss monster isn't half bad either as it can be a big beat stick and shut down plays from extra deck cards based off the card that is attached to it. Alternative Boss monster for this deck are Quintet magician and Underworld goddess, as one is a board wipe and can't be destroyed by card effects while the other can negate and stall and tribute your opponent's monster, works really well with I:P as you can cause disruption during your opponent's turn. Honnorable mentions for disruptive/boss monsters are ruddy rose or Chengying as they can help out by puting use into Dimension shifter if you see him in your hand whilst having cards in your graveyard. Chengying is a good general card and ruddy rose can possibly give Dimension shifter more value as it does bannish all cards in both gys, it could also take advantge of having sauge de fleur or evil thorn.

Combo Plays:

Litterally everything can combo into eachother, just be mindful when using Martha or Vadis as they lock you into exosister for the turn, General combos are:

S.Summon Martha and xyz summon into kaspitell or mikails (your preference) add pax and elis for guareenteed magnifica or for extended plays

N.summon zoroa, S.Summon another 4* spellcaster from your hand Synchro summon your boss magistus monster or extenders/negates, OR xyz summon Kaspitell or Mikailis, Grab pax to get martha, or just get martha with kaspitell, Xyz summon your opposite option use effect to grab another extender for later, Xyz summon mikailis and Kaspitell into Magnifica.

With Rillionia, same thing as zoroa except you have to grab trimagistus

with summoner monk, same thing as Zoroa except you Have to have a spell card in your hand

However, summoning the alternative boss monsters is harder but can be a game changer in your duel.

For Ruddy rose and Chengying You have to have a normal summon open and have zoroa on the field or S.Summoned with Trimagistus or monk (who should be on the field already or is also S.Summoned by Trimagistus) then tribute Monk or another monster S.Summoned by Monk or Zoroa With Dimesion Shifter then, synchro into those monsters.

For Quintet Magician very rewarding to summon but it is the hardest to summon, and unless you can play and search or have magicalized fusion in your hand ready your going to have a hard time with this one. If you plan to use magicalized fusion I recomend playing 1-2 Keeper of dragon magic as he is a lv 4 and can search "fusion" or "Polymerization" but he is a Dragon which can ruin ur magistus plays. If playing without keeper you need Zoroa and/or Monk and/or Rillionia, a non-copy 4* spellcaster, trimagistus, and a throw away spell card. there are exceptions depending on your hand variation which I will go over.

if you Don't have zoroa:

Activate trimagistus, S.Summon Rillionia or Monk and nomral summon the other, use both effect to grab fusion spell card and Zoroa, use Zoroa effect to equip artemis, S.Summon 4*star W/ zoroa effect, use artemis to grab crowley, then Fusion Summon.

if you Don't have Rillionia:

Samething as before just switching places with Rillionia and Zoroa.

if you Don't have monk, you must have 2 4* spellcasters or 1 and a Pax instead of a throw away spell:

activate Trimagistus, S.summon Rillionia or zoroa normal summon the other, equip artemis, use artemis to grab crowley, use Rillionia to grab fusion spell, fusion summon.

Weaknesses: Hand traps Go BRRR on this deck, back row cards do get annoying but are much easier to deal with. Going with the Alternate Boss summons, depending on what your summoning, is quite the risk as it can and will burn through ur mats from your hand, field, and/or graveyard. In my opinion with the way I've made this deck tho its somewhat comfortable going second and having Dimension shifter turn 0/1 works wonders against your opponent and their hand traps. you could also run carpedivem to negate monster effects with each xyz summon and add another layer of protection to your exosister and spell/trap removal.
