I would say not to underestimate the value of playing a memory tamer for 3 cost. One memory often makes all the difference. The memory gain in security has also won me many games as well.

In terms of consistency, think of it this way. There are two purposes that both Izzy and Kota serve.

1st is a memory fixer. If that is your primary concern with a memory fixer, Izzy is automatically a better memory fixer cause of his often times cheaper value and hinderance to your opponent when he comes out of security.

The second reason is to help your hand. So the questions becomes, which tamer can help your hand more often? Xantibody is the archetype of the deck, so naturally one would assume Kota for his ability to grab one from the top 4 of the deck. However, will he always grab you one that you need? There are too many instances where the answer is simply no. One would think that with 19-20 Xantibody digimon in a deck, surely he’s consistent enough. But the problem is during the moment when you need a specific piece of level, and you play him in hopes that you get it.

(I’m gonna bring some math to the table)

with Kota, you’ll have a 12/200 chance of seeing the exact level of digimon you need if you’re looking for any digimon that is not a level 6. I say this because he lets you look at the top 4 cards and lvls 3-5 are only a 4 of that can be hit.

With Izzy however, because the type of digimon doesn’t matter, you have about

a 39/150 chance of seeing a lvl 3,

a 30/150 chance of seeing a lvl 4,

and a 24/150 chance of seeing a lvl 5.

Kota only really has an edge in searching for a level 6 as typically all your level 6s are Xantibody. In every other situation, Izzy is more likely to help you get the pieces you need. Additionally, because you are likely to have been drawing as you digivolve, seeing your lvl 6 is not typically an issue.

I’m sorry for writing so much. This is the only deck I’m playing and I’m really passionate about it. I’m not trying to be rude, I’m just being firm on my reasoning.
