(As this Saga enters and after your draw step, add a lore counter.)
I, II, III — Create a token that's a copy of target nonlegendary enchantment you control. It gains haste. If it's a Saga, put up to three lore counters on it. Sacrifice it at the beginning of your next end step.
IV — Add {W}{W}, {U}{U}, {B}{B}, {R}{R}, and {G}{G}. Exile Esper Terra, then return it to the battlefield (front face up).
