Mecha Phantom Beast Synchro
Use Blue Impala in a Mecha Phantom Beast deck so that you can easily Synchro summon their powerful monsters. Putting Blue Impala in a Mecha Phantom Beast ensures you have Mecha Phantom Beasts to use as Synchro material and Machine-type Synchro monsters to go into.
Blue Impala does not restrict you from summon non-Mecha Phantom Beast Synchro monsters as long as they are Machine-type and you use Mecha Phantom Beast monsters as the Synchro materials. Here are some other monsters you can summon.
