"Found myself a Taiga and Tropical Island . I doubt that it'll make a huge difference, but I gotta give the swarm what asks for."

I assure you that the inclusion of what i'm assuming are Revised dual lands make a massive difference - just in subtle ways:

1. For example you crack a Wooded Foothills to search for a "Forest" but you only have a handful of Blue cards/creatures - you can acquire that Tropical Island and not have to pay an additional 2 life to have it come into play untapped. Sure, 2 life isn't that consequential...but it makes a difference when you have to do that every time you want to try and color fix your mana. Those little shocks for land really add up over time.

2. Having an additional array of typed lands that can be fetched helps in color fixing - this will help you get the right mana at the right time which is the biggest hurdle all 5c decks have.

Acquiring Dual lands is no small thing - you are part of an elite few number of deck builders that have gained access to the mecca of lands.

You're 100% right, 5 duals to go and maybe a cradle someday.

I've decided to invest in big cards instead of building a new deck every two weeks. Sold a bunch of cedh staples that I'll never be using in my playgroup.

Thank you for your kind words. You are, as always, an inspiration.
