If you control 2 Xyz Monsters that have the highest Rank, target 1 of them to activate this card.
If the "During your Draw Phase, if this card is in your Graveyard, instead of conducting your normal draw: You can add this card from your Graveyard to your hand." effect is activated and the effect of "D.D. Crow" is activated in a Chain, even if this card is no longer in the Graveyard, since this effect was activated instead of conducting the normal draw, the normal draw cannot be performed afterwards. The "You cannot Special Summon during the turn you activate this card, except by the effect of "Rank-Up-Magic Astral Force"." is also applied.
