I can't even remember the last expansion I have...Kobolds?

Anyway  I love(d) playing ladder and didn't really care much for WILD.  

What xpacs do I need to purchase to play standard?  Are all of the below needed?  Which will be the first to leave the rota?  Should I buy it anyway?

• The Witchwood
• The Boomsday Project
• Rastakhan's Rumble

• Rise of Shadows
• Saviors of Uldum

just a little guidance please!

witchwood, boomsday, and rumble are about to rotate out within the next 3-4 months, shadows uldoom and dragons will be standard for another year, if you have the means, u can get some more of the first 3, but i wouldnt advise

ahhh!  that's the advice i needed.  Thank you Osirian!!

Definitely buy 10 from each so you can get the guaranteed legendary from each set though.
