Extreme credit to Programmer_112 because this is his deck idea, but I wanted to make my own version complete with a sideboard and a few changes I think were necessary. For the original, see The reason I have no friends($10Blue Controllolol).
As for the deck itself, you bounce their lands every turn until you draw Jace's Archivist and then you get to draw 6-7 cards per turn. Howling Mine helps you get there and once you have excessive card draw you use Elixir of Immortality to win by mill.
I'm still working on the sideboard and suggestions are welcome. Right now it's geared to beat RDW mainly. This deck has a lot of trouble with forcefeed, but it isn't a common modern deck so I'm not too worried. Unfortunately most modern decks can survive on 2 mana which kills us, but if we can make it to turn 4-5 without too much trouble, then we usually win.
For a version with more lifegain to counter aggro, see Boomerangs with a Splash of White
For a full budget version replace Howling Mine with Dictate of Kruphix and replace Spell Pierce with Stubborn Denial.
For a non-budget version, see Boomerangs with no budget
If $500 is too much but $100 is not, then do get a playset of Chalice of the Void because as soon as that hits the field, it's game. It is consistently amazing against all decks that usually beat this, so I highly recommend it. It is expensive, but well worth it if you are willing to pay to win.
If $100 is too much, then spend $20 to get a playset of Trinisphere because although it isn't as good as Chalice of the Void, it is still a very strong card against RDW and such because hopefully they won't have 3 mana. If you go this path, also spend an extra $10 to get Spell Pierce instead of Negate because it costs less mana and will always hit.
