Treeborn Frog can easily be used as a single tribute to summon this card. Use Soul Exchange to use one of your opponent's monster as tribute. You can also use Enemy Controller tribute control effect to use your opponent’s monster as tribute.
Berlineth the Firestorm Vassal is the direct combo synergy to Thestalos the Fire Monarch, because Berlineth’s effect when it was used to Tribute Summon, will be triggered to banish 1 card from your opponent’s hand until the End Phase (Your choice of card). Pyrorex is able to be Special Summoned when your graveyard has exactly 5 FIRE monsters.

I've loved monarchs as a card type for ages and when they got more support in the TCG I was so excited, but then they ended up too strong!
I'd like to see more of them, so far we've had Delg the dark monarch, Angmarl the fiendish monarch, and now Thestalos... if they ever give us mega monarchs we're doomed.
I think thestalos the mega monarch has been datamined , we may see it shortly this month

So I got this dude twice in 5 packs (I'm F2P and reset the box after every pack cuz I own a playset of nearly any SR). Is it worth to build a deck around him? I have no Berlineth, no Treeborn Drog and only 1 Soul Exchange.
I think mobius could be released in DL at 3, Raiza would probably be too powerful, and Caius maybe in time.. or as a 1 of. Granmarg is not too good since most set cards will be backrow that is mostly chainable, and zaborg's mandatory effect could hurt you too especially when you use SE.
justification for mobius at 3: tribute summoning in itself is slow, costly and not always guaranteed, being able to destroy 2 spells/traps is very good but again, some could be chainable. And a lot of skills already involve a +1 field spell card, meanwhile any monarch deck would be heavily reliant on skills like restart to not totally brick, even though the last might not be an argument to some...
^except for the fact that raiza is way more versatile, consistent and devastating than red Dragon ninja. Being able to deal with everything on the field and not just set cards, while setting you're opponent back a turn with their draw, with no constraints of having ninja cards in the graveyard, raiza would very much be gamechanging at 3.

What kind of deck that suits him? Only UR that I can have from the pack, and I'd like to try it
