You're normal summoning, you need enough tributes to summon it.
Guys, this card is pretty fun to play. Using Legion the Fiend Jester and Blue Dragon Summoner, you can summon powerful spellcasters while still drawing more monsters to summon. It also synergies with Yugi's Yami ability.
It actually works! At full 4000LP (opponent) you just need at least 4 monsters on hand and 1 on playing field to inflict 800 points of damage each time you activate Man-Thro'Tro' effect to win or whatever the opponents LP is at. The effect is immediately infinite and cry havoc is continuous so in your "main phase" you can win but then again its hard to draw exactly just those 2 cards and the right amount of monsters or you'll deck out. Best to play both at same time with 1 monster already on the field for tributing to catch your opponent offguard since Man stats are 1000/1000 only leaving them scratching their head what just happen?
