Medieval Wars alliance name

Hi everyone! So as you all know, we are going to join Medieval Wars (MW). We are going to create a new alliance. The Puzzle Patzers and Unstoppable Forces have offered to join us. 

However, we need an alliance name. The owners of these three clubs have met and we have decided on a few different name options. Tell me what you think!

1. The PDF Alliance (Puzzle Dino Forces Alliance) 

2. The Imperial Front

3. The Checkmate Federation

Respond in the forum with a number 1-3 to tell us which name is the best. Thanks!
