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.
