Imagine casting a board wipe with a Final Fantasy twist
In a frosty forest, Glaceon is posed elegantly underneath a glowing source of light, illuminating the monster and helping it stand out among the beautiful environment
The reanimated creature also gets to attack, and this synergizes with efficient creatures, creatures with additional downsides when cast, or simply creatures that have good enter effects
In this case we have a six-mana flying Phoenix that brings a free spell to the party and it'll cascade for you all day and night
Infinite mana equals infinite untaps, equals infinite uses of Staff of Nin or another lethal artifact ability
If you can safely cast her with an X value of at least seven, then you can activate her -6 ability straight away, which takes two of your lands and untaps them, turns them into 5/5 elemental creatures with flying and haste
