1 EARTH Tuner + 1 or more non-Tuner monsters When this card destroys an opponent's monster by battle and sends it to the Graveyard: You can Special Summon that monster to your field in Defense Position.
all synchro ace cards are in skills or boxes where you can obtain it by spending gems or money ... but I doubt they will release Goyo Guardian even in a box as it is too good level 6 monster with high atk/def
At last, Goyo Guardian has a summon animation. Not a bad animation at all
They're not going to give an animation to Stygian Sergeants or Dark Diviner...
They might go back and give him one for Goyo Guardian eventually, but I could also see him just not having one, like Ishizu. (Who knows, maybe their increased number of new unlockable characters put too much of a strain on their animation budget).
Goyo Guardian is an example of the last one, it originally can be summoned using any Tuner. But a generic synchro with 2800 ATK and monster stealing effect was later on deemed too powerful as newer cards that can easily abuse it shows up. As a result, it had to be banned.
you know konami should stop with the errata bullshit !!
wording change a little means a lot in terms of speed. but changes in the summon or effect practically broken the card not becoming good at all. ERRATA !! KONAMI !!
