The most fundamental change in [Thunder God II] was that it no longer needed to fully charge [Thunder God Heart] to switch between [Therian Forme] and [Incarnate Forme].
Second, the upper limit of [Thunder God Heart] had been greatly enhanced.
When [Thunder God Heart] entered its final stage, [Thundurus]'s three core stats would increase by 200%! This took it directly from the 20,000 tier to the 30,000 tier!
At that point, [Thundurus] would undoubtedly stand at the pinnacle among [God Cards].

Advancing through each stage required thirty seconds.
Going from the first stage to the fifth required one hundred and twenty seconds, or four turns.
If it was a Tribute Summon without any requirement for Electric Type element concentration, then it had to start from zero and spend an additional thirty seconds entering the first
