That's why keeping him intangible so he can't do any damage which negates any possibility for recklessness in game.

I'm also a little confused where you're saying two from? I'm not requesting any additional now, just that the option for Diabound to be able to be invisible not be put off limits for the long term (since I assume "a while a while" is long term) since with him only being able to be summoned, and still being visible, he's a detriment more than anything else since any time he was summoned there would be the huge risk of being found out and it putting Bakura in danger.

And to clarify, at this point, Bakura isn't gaining any of Diabound's abilities, just the ability to summon him. Diabound being intangible is to prevent things from being damaged or broken due to Diabound's size and to keep the echo from being a big thing. As he is being requested by this echo, Diabound would be pretty useless, and I really would like him not to be locked into uselessness for an extended period of time.

[and also as a side note: Yami Bakura and Thief King Bakura are major combatants so to imply that since this Bakura more closely resembles the non combatant version of the three at this time that he needs to stay in that role is a little off putting.]
