Since there are expectations that after DTT ban there will be less decks with Islands, I am currently thinking about adding to my deck some cards to transform lands into Islands. So far I have four options:
- Tidal Warrior - Pros: for U you have another 1/1 merfolk that can attack, block, and can be pumped; can be cast using Caverns of Souls and will work well with Chalice on 1; temporarily transforms one land into an Island. Cons: cannot be used to save non-basic lands from Wastelanding.
- Aquitect's Will - Pros: cost only U, your opponent gets an Island, you draw a card. Cons: uncastable with Chalice on 1, doesn't change land type and land characteristics.
- Sea's Claim - Pros: cost only U, permanently transforms one land into an Island; Cons: Chalice on 1.
- Spreading Seas - Pros: permanently transforms one land into an Island, you draw a card, works well with Chalice on 1. Cons: cost 1U.
Tidal Warrior looks like the best option here, especially assuming that we will have Chalices in MD. However, I am curious to hear if anyone experimented with other options.
