Random Generator gave me Loxodon Convert and Castle Raptors. I tried letting gatherer randomize cards until I could get an appropriate person to make this quote. Unfortunately, you can't make the randomizer do your bidding, so I went and looked up Abbey Matron instead. Seems Halina doesn't like them, and I doubt she'd like these birds, either.

Is that meant to be "When ~ becomes tapped, it gets +2/-2 UEOT", or "As long as ~ is tapped, it [has/gets] +2/-2"?

Not UEOT, just on when tapped, similar, in theory to the Castle Raptors when untapped. I think I prefer "when attacking" since it gets the message across clearler, but I'd rather have it line up, and it is such a small change (albeit, very important for red sorceries). I find it funny. The three different takes that are roughly the same, but all do different things when presented with a Twiddle.
