Fascinatingly, rarities for DPBC (TCG Version) are different from DP16 (Japanese version)
During either player’s Battle Step: You can Special Summon this card from your hand, and if you do, gain 1000 LP. YOu can only use this effect of “Juragedo” once per turn. During either player’s turn: You can Tribute this card, then target 1 face-up monster you control, it gains 1000 ATK until the end of the next turn.
Yes, it’s either a Common or a Super.
And for those curious, Konami explains the Battle Step in their article.
