I make naught the opponent of this duel, and choose Island Fortress as the Battlefield.

Tyguys forces:

Mechanical Stealthy(2) Giant(3) Digging(3) Fire-Breathing(3) Surefooted(2) Armoured(2) Swimming(4) Sponge[19]; 
Proud Trumpeting (tactic)[0];
Winged(4) Fire-Breathing(3) Swimming(4) Giant(3) Armored(2) Numbat [16];
Mechanical Venomous(2) Leaping(3) Giant(3) Digging(3) Fire-Breathing(3) Surefooted(2) Armoured(2) Swimming(4) Sponge [22]; 
Spectral Venomous(2) Leaping(3) Giant(3) Digging(3) Fire-Breathing(3) Surefooted(2) Armoured(2) Swimming(4) Sponge[22];

Naught’s forces:
1. Stealthy Leaping(2) Giant(3) Digging(3) Fire-breathing(3) Surefooted(2) Armored(2) Swimming(4) Sponge(6*) [25/22]
2. Leaping(2) Digging(3) Fire-breathing(3) Surefooted(2) Armored(2) Swimming(4) Sponge (6*) [22/19]
3. Pack Hunting (Sponge)[0]
4. Leaping(2) Giant(3) Digging(3) Fire-breathing(3) Surefooted(2) Armored(2) Swimming(4) Venomous(2) Sponge(6*) [27/24]
5. Pack Hunting (Sponge)[0]

Tyguy6 wins slots 5 and 3
Naught wins slots 1, 2 and 4

Provisionally, Naught is triumphant, IF his list is a valid plan. whether or not both pack huntings apply doesn’t change the outcome. Whether a single one applies DOES change the outcome, making #1 a tie and changing #4 to a win by Tyguy6.

I believe Naught is the triumphant. I fully expect this to be settled by a vote by the assembled wizards. I also believe that this result decides the dynasty.
