So a good majority of the good aggro cards would not get picked up because my cube contained a lot of dragons and other large creatures. That's partly my fault though as my first cube incarnation was very Timmy focused. I've since moved away from that and have started to put some more support for fast aggro.
With that said, my cube can support Wx aggro quite easily now I think. There are a number of fairly efficient white creatures like
- Soldier of the Pantheon
- Phalanx Leader
- Kor Skyfisher
- Accorder Paladin
- Fencing Ace
- White Knight
- Blade Splicer
- Fabled Hero
- Porcelain Legionnaire
- Spear of Heliod
- Griffin Guide
- Armored Ascension
- Apostle's Blessing
- Emerge Unscathed
- Darksteel Axe
- Silver-Inlaid Dagger
I don't think there is a best partner as each colour provides a unique quality to the aggro deck but here are few cards I would look for in each of the possible colour pairings with white.
I wanted to go WR Aggro I would look to pick up
- Anax and Cymede
- Figure of Destiny
- Sunhome Guildmage
- Boros Swiftblade
- Akroan Hoplite
- Firemane Avenger
- Tajic, Blade of the Legion
- any burn spell
If I wanted to go WB I would look for
Black gives you access to some more early power plus removal to take out some of the larger things your small creatures can't deal with. Also provides reach with some of the Extort creatures.
WG would go
More efficient early creatures and unrivaled mid-game power too. Also provides more heroic creatures and some nice giant creatures if your early barrage can't finish off your opponent.
WU would want
- Daxos of Meletis
- Lyev Skyknight
- Skymark Roc
- Ascended Lawmage
- Cloudfin Raptor
- Invisible Stalker
- any bounce spell or counter
