equipping an equipped creature

[Jean le Chauve]

muppet reported:
I think you should not be able to pay an equip cost to equip a creature currently equipped by the equipment.

currently you can at least with lashwrithe.

dinghammer:
The rules allow it.

702.6a Equip is an activated ability of Equipment cards. "Equip [cost]" means "[Cost]: Attach this permanent to target creature you control. Activate this ability only any time you could cast a sorcery."

Is it giving double bonuses or something?

muppet:
reply no I just happened to read a bit which said attach to another creature you control but seems i had an out of date rule.

It is simply part of the ai is mad when it has equipment in general problem. It will happily use all its life equiping lashwrithe over and over to the same creature for example.
