- I play Lone Rider and gain 1 life through Soul Warden.
- I play another creature and gain another 1 life through Soul Warden.
- Now the end step occurs. Because I gained life, I get a 5/5 token through "Crested Sunmare".
- That token allows me to get another 1 life through Sould Warden.
Does that mean that I now gained three life and can transform "Lone Rider", or did the 1 last required life come "too late" for Lone Rider to transform since we are already in the end step?
OR can I choose which ability is checked first, Sunmare's or the Rider's?
