This one is Light Played, so quite affordable
This two-mana equipment gives your equipped creature haste and hexproof, letting you attack as soon as it comes into play but also letting you dodge any removal your opponents might have
It can only be cast through suspending it, and with time traveling you can cast it much quicker instead of having to wait four turns
I appreciate this green instant alongside commanders like Lathiel, the Bounteous Dawn and Bilbo, Birthday Celebrant that care about high bursts of lifegain
It also gives you the 1-2 punch effect that really grates on certain opponents
For example, you can't cast a creature card with mayhem you couldn't normally cast during an opponent's turn, even if you discard that card during an opponent's turn.
