RipTide Mangler w/BoneSplitter, targeting itself

[LotusHead]

If I equip Riptide Mangler with a BoneSplitter (gives +2/+0) or enchant with Unholy Strength (give +2/+1) or even give it a +1/+1 counter (by say, Graft), can I use its ability to target itself, thus improving its unmodified power?

Example: it is 0/3, then I equip with Bonsplitter making it a 2/3. I pay 1U, targeting itself to make its power 2, then its bonesplitter bonus ramps it up to a 4/3.

Riptide Mangler 1U
Creature-  Beast
0/3
Casting cost: 1U

Oracle text: 1U: Change Riptide Mangler’s power to target creature’s power. (It doesn’t change back at end of turn.)

Intuition tells me that I can do this (and have an uber cool guy), but I am not sure.

To make it 4/3 after using its ability, you need to move the bonesplitter to another creature , and then move it again to the riptide.
If you have another creature and enough mana it would work.

Not working with +1/+1 counters or enchantments (unless enchantment is bounced and replayed).

I hope the questions to the judge are clear enough to understand how it works.

That Ask the Judge is out of date. The original post is correct.

418.5a The values of an object's characteristics are determined by starting with the actual object, then applying continuous effects in a series of layers in the following order: (1) copy effects (see rule 503, "Copying Objects"); (2) control-changing effects; (3) text-changing effects; (4) type-, subtype-, and supertype-changing effects; (5) all other continuous effects, except those that change power and/or toughness; and (6) power- and/or toughness-changing effects.
          Inside each layer from 1 through 5, apply effects from characteristic-setting abilities first, then all other effects. Inside layer 6, apply effects in a series of sublayers in the following order: (6a) effects from characteristic-setting abilities; (6b) all other effects not specifically applied in 6c, 6d, or 6e; (6c) changes from counters; (6d) effects from static abilities that modify power and/or toughness but don't set power and/or toughness to a specific number or value; and (6e) effects that switch a creature's power and toughness. See also the rules for timestamp order and dependency (rules 418.5b-418.5g).

Lotushead,

I had used mangler in combination with pemmins aura in a casual mono blue deck I played with. It makes the mangler into a ghetto morphling, that can do all the same tricks u said, although you have to pay to pump/change it's power. But it gives it flying and untargetabilty and untap.Hot!

I remember playing a mistform mask on someones DSC. Them letting it resolve and me making that bad ass a wall every turn... Fun times
