They accomplished this in a few ways: The Planeswalker Cards We already talked about this one, but obviously this was key in allowing players to get their hands on both the pre- and post-ignited spark characters while also finding a very splashy and mechanical way to represent the spark moment for each character
This will also turn your dorks into an Ancient Greenwarden and play lands from your graveyard, Carnage Tyrant to make it a beater, Grunn, the Lonely King to double its power when it swings alone, Kamahl, Fist of Krosa to Overrun and make lands dorks, Multani, Maro-Sorcerer to grow massively in size and get shroud, Nemata, Grove Guardian to make a bunch of tokens, Primordial Sage and Soul of the Harvest to draw cards, Rampaging Baloths to landfall and game win, and that's just one casting cost
Powerful things to curve out into and big incentives are possible, but this goes back to the previous point
this could be the top-end of a white weenie deck that leverages the 0 for lethal, a piece of a midrange shell that generates tons of attackers, or a consistent source of counters or sacrifice fodder
