While it may take a bit to build up to, thanks to Dragon-God only coming in at 4 loyalty, his -8 ability can be an immediate victory if your opponents don't control a legendary creature or planeswalker
Voltorb and Electrode serve as great substitutes until you get the ball rolling with your EX cards
Scarily, that token copy enters with loyalty counters equal to the power of the creature you sacrificed to the loyalty ability, letting you easily throw his ultimate ability off straight away We're not quite as likely to see casualty return on a Planeswalker as we are compleated, as it was a set mechanic for Streets of New Capenna
If you control more than one legendary creature with the same name and the "legend rule" begins applying again (perhaps because Council of Reeds leaves the battlefield), you'll immediately have to comply with the rule and put all but one of those permanents into the graveyard
