I like the idea of putting the Jittes on mainboard, cause they are always useful.
Maybe I could play 2 pierces and 2 Jittes with other 2 pierces sideboard instead of 4 Pierces mainboard.
The main reason I cut them was after I considered their usefulness in the Burn matchups.
Theoretically Standstill should be a bomb here, but I realized they just make it pop, let us draw 3 cards, then simply proceed to win. They don't care at all about our 3 card advantage when they are a few more burn spells to kill us, cause we can't out-counter them forever. Instead, they are happy we tapped out without casting a threat or leaving mana open for a pierce.
Standstill simply slows us down in that matchup, and I really think a Spell pierce is just better than it.
And in the RUG matchup?
It's pretty useless as well, since they have more denial than us and their board state will probably be better than ours when we should cast Standstill.
Against combo we can play 12 counters and we have a pretty fast clock, so we should be in a good spot also without Standstills.
I feel Standstill right now is in most cases just a waste of 2 mana, which could be used to cast a Lord or to keep that mana open for a counter.
Since I cut standstill to play more counters/creatures my matchups have improved a lot, so I don't think I'll look back for them.
I think Reejereys are still very good, but maybe 4 copies are too many in some cases.
I wouldn't cut them completely, cause 3 Images would be too many (what if we have only them in hand with nothing to copy?) and also 3 Commanders are not the right number imho, 2 is great for both of them.
Reejerey should be 3 or 4 imho, not less cause we have no valid substitutes and we don't want to lower our creature count.
