Celestial, most level 11's have stats over 3000, except Yubel - Terror incarnate (but lets not get started on that card) but until its effect becomes active, Its just a normal monster. (and hey at least its not Nekroz of Sophia...)

Just my opinion on Celestial (I know it's late).

All Level 11 cards have some non-normal summon condition. Yubel - Terror Incarnate requires Yubel to be summoned, Star Eater is a Synchro, Infernoid Tierra is a pretty difficult Fusion Summon (I think), Hyper Psychic Blaster/Assault Mode requires Assault Mode Activate, Sophia needs a Fusion, Ritual, Synchro and XYZ monster on the field to be summoned, Nekroz of Sophia has a quite specific conditions (Although those conditions are usually easily met) and Gate Guardian requires the greatest trio in the game.

All of the Level11 Effect Monsters have the text "Cannot be Normal Summoned or Set. Must be Special Summoned by "Yubel", and cannot be Special Summoned by other ways." or some form of it. Gate Guardian can be Special Summoned, but he has to first has to be played on the field by fulfilling his summon condition.
