Usually we just see updates for new mechanics, but in this case we see some modifications of existing advanced mechanics
As the game takes shape, you want to look for cards that are much better for them than they are for you
It's no surprise that when you pair Darkrai with one of the most popular Pokmon of all time, an Eeveelution with multiple hot chase cards to its name, it results in a popular card
Joraga is a more powerful card than the other one drop ramp dorks but it does come with a risk
Ive never cast it and had another player pay into without being a graveyard deck themselves
Still, the rest of your deck needs to be filled with something, and if it wasnt awful Ritual monsters or a single, useless copy of Polymerization, it was more vanilla beaters
