First off, I've played everything from UWR, to UR, to BUG, to UB, to UW in modern since its inception. The CA suite has always been a sort of...contentious part of control decks in modern as they've mostly been clunky and expensive (and HI at 4 mana isn't an exception), however I wanted to hear others game experiences and testing with the card.

A little background: I won my local 40 player PPTQ with UB control with 2 HI's, and since Trophy was printed, slid into BUg as it answers a huge hole for the deck. HI performed pretty well and since I've been on and off 1-2. For those who think LSV and Ben Stark are more correct in their evaluation have many tested with 3-4 and how has it performed in this meta? The reason I'm asking is that the RPTQ is coming up at the end of this month and I can't playtest as much as I want, so I'm very interested to hear others takes on this.

The other options available have some serious drawbacks where HI floor is cycling (which given the preponderance of lands in our decks, tends to increase our odds of flooding). AV if its not in your opening hand is quite poor and doesn't interact well on the speed axis of the format. It is quite good on the play against fair decks, but is vulnerable to discard on the draw, and it can't be flashbacked by Snap. Since Non-UW decks don't have access to Teferi as a CA engine (and JTMS is far inferior in the format without Terminus imho) I'm wondering what has worked best for those decks in practice.

TL;DR - Is it right to play 0-4 HI and in practice what have people found when playing 3-4 (tend to flood, too clunky, flexibility means cycling early is fine and inspiration is fine at that stage of the game, etc.)?
