How the hell do I defeat Sliver Hive?

[Siege Aeterna]

I've been on this opponent for the past six hours or so, and tried dozens of different deck combinations, to no avail.

Killl the slivers as they come out

build a deck to beat them - black red, I don't know really. I can't beleive this is the 2nd thread on this in 2 pages.

Use burns and kill spells.

I beat this using Life and Death (White and Black deck), which has a few kill/exile/exile on block/defend spells extra in it.

Also to be a bit more constructive, be merciless with what hand you take. Don't be afraid to restart duel at any time. Edit your deck as soon as you see something not working towards winning asap.

But the biggest advice there, as to any single player challenge, take a REALLY good hand. Just keep restarting the game until you have an almost unbeatable hand

A few tips.
1) put it on easy
2) grind until you have unlocked all available cards in the "explore" option.
3) sliver is about speed and synergy. You need to keep the number of his creatures on the battlefield as low as possible at all times. You can counter with any cards that kill/burn/exile/render useless. Create a deck with a lot of those.
4) Wait until you have a really good starter hand.

Blue helps. Flying creatures for that pesky Flying Sliver and counterspells/bounce o stop the synergyyy

Thanks for the suggestions. I ended up making a deck comprised almost entirely of Instants, and that finally did the trick.
