Mulcharmy Fuwalos, and how to ignore your Extra Deck

Mulcharmy Fuwalos Level 4 WIND Winged Beast If you control no cards (Quick Effect): You can discard this card; apply these effects this turn. ● Each time your opponent Special Summons a monster(s) from the Deck and/or Extra Deck, immediately draw 1 card. ● Once, during this End Phase, if the number of cards in your hand is more than the number of cards your opponent controls +6, you must randomly shuffle cards from your hand into the Deck so the number in your hand equals the number your opponent controls +6. You can only activate 1 other "Mulcharmy" monster effect, the turn you activate this effect. ATK 100 | DEF 600

To keep it short - you see this card and don't open Ash Blossom & Joyous Spring, Called by the Grave or Crossout Designator (if you're running Fuwalos yourself), you stop Special Summoning from the Extra Deck, unless you're confident your opponent won't be able to beat you, even with 3-5 extra cards in their hand.

So, what are our options?

The first option is doing the most basic combo we have, the 1-card Ponix combo. This gives your opponent no draws at all as we don't use the Extra Deck at all during our turn, although it does mean our endboard is much weaker.

Another option depends on our hand. If we open Ponix, the plan is to cut the 1.5-card combo short, and end on Duelittle Chimera and Salamangreat Almiraj. This is an awkward endboard, but if things go well, you're only giving them 2 draws while you can potentially go +3 and have some interruptions to use on your opponent. Instructions are here.

If you open Ulcanix, good news! You can make Amblowhale with just two draws. See the combo here.

The last, and riskiest option, is to play normally through Fuwalos. Keep in mind your opponent could draw 5 cards from it, which in most cases, puts you at a big disadvantage.
