Mirror Force wont work in every situation, but when its effective, its really effectiveso much so that fans keep using it, even though more modern cards have since been issued
Adds: I've added more creatures that can be reanimated by Terra, Herald of Hope, along with two extra combats such as Fear of Missing Out which allows us to mill + reanimate more
In terms of how Modern looks now, Arclight Phoenix decks of various flavors do not fare particularly well with a resolved Trinisphere
Still, a game like this does need to evolve with each new set in order to keep a recurring interest and look like a serious contender against the likes of MtG, Yu-Gi-Oh or even Pokmon
Yes, you still get the lands, but a big part of the fun is the cards body
