My stance on that sort of thing is that you just include multiple cards in the pick. It's another thing to explain but it's sort of simpler and less stressful. I'm not sure how they should be distributed but I was sort of assuming you might do this with two tri coloured spells.
What are some cards or themes you'd like to cube if they had more support that was attractive to a variety of archetypes?
Does anyone have any ideas that make white weenie more fun to play or more powerful or more interactive. I know it has access to a lot of great spells through being white but often everyone else wants these cards more and boy do the wraths and balance type cards ever feel like they are not in your colour.
One of my first ideas to help white dorks feel more like a big boy deck
Glory's Guide
Creature - Spirit
When Glory's Guide enters the battlefield search your library for a creature card with converted mana cost 1 or less, reveal it, put it into your hand and then shuffle your library.
1/1
When I design cards like this I feel like they are going to be obviously too powerful and probably aren't solving the problem:
Enchantment
When CARD enters the battlefield put 2 1/1 white soldier creature tokens into play.
Creatures you control get +1/+1.
This idea is obviously open to editing though.
Glorious Anthem + Exalted sounds like a fair card though.
Do white creature decks do anything particularly interesting? Is attacking with more than one creature interesting? Is protection or say burning out your hand quickly an area that can be exploited?
