[casthaven]Glimpse the Unthinkable[/casthaven] is now a card people can playtest with, meaning UB Mill will go from a Modern deck that looks cool and nobody plays to a Modern deck proven to be unplayable
I love this with Commanders with evasion already like Azorius's Brago, King Eternal that flies or getting trample as a modified dork with Kodama of the West Tree
This will likely end up as a 99 card, either in a big red brew or some kind of Reanimator list
Formidable Speaker will probably do the bulk of its work in Commander, where tutors, while controversial, are at their best
#3 And yeah you should be very wary of defensive strategies because they are easier to a) pilot and b) draft
If the target creature card is an illegal target as General Leo Cristophe's ability tries to resolve, it won't resolve and none of its effects will happen
