Wizards spread the word earlier this week to its distributors that there is a reprint of the Deck Builder's Toolkit coming, and with this reprint they are going to be rotating all the booster packs included in the kit. Previously the Toolkit included Magic 2010, a selection from Zendikar, Worldwake, Shards of Alara, Conflux and M10. The reprint will contain Magic 2011, Zendikar, Worldwake and Rise of the Eldrazi booster packs.

Update: We do not know of any changes occurring to the individual cards, only the booster packs in the kits. These kits don't have a set street date, but they will begin shipping in August according to our sources.
