Revision to Descend mechanic

I have not seen the Descend mechanic affect my games or play any discernible difference, mostly because I believe it is too difficult to match the descend support 3+ times in a match. For example, for cards that have a Descend 4 requirement, you’d have to match the Descend support 4 times (likely 4 turns) which is a little too long and focused in my opinio, especially if the Descend support is not a positive gem color for your Planeswalker and/or the support is placed in a corner of the field.

My suggestion would be:

-make the Descend support have a mana field like aura;
-matching gems in the mana field increases the Descend support by 1 level; and,
-matching the Descend support itself increases the Descend support level by 2
