The Hawks are one of Africa's representatives at the World Cup
Paraguay fought back from 2-1 down at half time to beat fellow World Cup qualifiers Togo 4-2 in the first game of a four-team tournament in the Iranian capital on Friday.
Paraguay will now face Macedonia in Sunday's final after the Balkan side beat Iran 2-1 in Friday's second match.
Iran will play Togo in the third-place playoff.
Paraguay's early pressure paid dividends in the 12th minute when Dante Lopez muscled past his marker and bobbled the ball over diving keeper Tchagnirou Ouronimini.
Togo equalised in the 33rd minute when Cherif-Toure Mamam thumped a penalty into the top right corner, beating a diving Miguel Cardenas.
Two minutes later, they went ahead when Soulemane Kobert converted from close-range.
But Paraguay rallied straight after half-time, launching wave after wave of attacks on the increasingly erratic Togo defenders who kept slipping on the rain-drenched pitch.
Lopez connected with a corner in the 51st minute, heading powerfully past Ouronimini.
Six minutes later Carlos Bonet struck from the edge of the box, getting a deflection off a Togolese defender that looped into the net.
Julio Dos Santos scored Paraguay's fourth in the 65th minute to confirm the South Americans dominance.
