So this is my Unchained build fro the February 2021 format. It's sooooo budget, but you can extend it by adding
Underworld Goddess of the Closed World.
Here I will show you the 2 main combos for the strategy.
The first combo is only by having
Unchained Twins - Aruha and any Unchained spell/trap
- the set card is destroyed and you special summon
Aruha
- you trigger the set card's floating effect to special summon
Unchained Twins - Sarama from your deck
- use
Sarama's effect, targeting the spell/trap in your GY
- that card is set to your field then you destroy
Sarama
- Sarama's floating effect special summons
Abominable Unchained Soul (you can trigger it's effect if you want)
- link the 2 monsters you have on the field into
Unchained Soul of Rage
Now you have a Link-2 monster on your field, who can link itself with an opponents monster during their Main Phase.
The second combo, which is an OTK if your opponent has no monsters on their field adn nothing in response to attacks, requires
Unchained Twins - Aruha,
Unchained Twins - Rakea and any Unchained spell/trap.
- you set the spell/trap
- pop it with
Aruha which is then special summoned
- the set card's floating effect triggers to special summon
Sarama
- normal summon
Rakea and proceed to Battle Phase
- attack with them for 4500 damage
- activate the quick effect of
Rakea to pop your
Aruha
- aruha's floating effect triggers, special summoning
Abominable Unchained Soul
- it's effect triggers, discarding the card that you have in your hand to pop your Sarama (or Rakea, it doesn't matter)
- it's floating effect triggers to special summon one of your Unchained monsters (doesn't matter which) and swing for game
So that's all for the combo tutorial, good luck!
