I hope this is in the right place. I've built a landfall deck with Ancient Greenwarden, Yarok, the Desecrated, and a bunch of cards with landfall (including Moraug). My question is this, say I have both Ancient Greenwarden and Yarok, the Desecrated out along with a Brushfire Elemental and I play a land. How many instances of the +2/+2 does the Brushfire Elemental get? I'm struggling to keep up with the math...
There is a Rulings Forum for questions like that and, as hoffmkr points out, using card tags is mandatory.
As to your question, each of those cards add one trigger. So, with both, you get 3 triggers instead of 1 for each Landfall trigger whenever a land enters since you get 2 extra triggers (one from Yarok and one from Greenwarden). So, Elemental gets +6/+6 total. Moraug would get you 3 extra combat phases. And so on for anything else with Landfall.
