I Miss PanharmoniconQuasiduplicate creatures with underrated etb effects or abilities.
Siren's Ruse to double up on etb triggers and protect creatures from removal.
1st target is
demanding dragon. I kinda want more removal in the deck to try to ensure its five to the face or getting rid of a hexproof/indestructible creature.
2nd target is
timestream navigator, for obvious reasons.
3rd target is
sailor of means for additional blocker and to get to 5 mana faster if lands are not coming.
Draw cards instead of removal for now.
Siren stormtamer is a useful 1cmc play, but not really on theme except for interacting with
siren's ruse.
I'll probably find better targets to duplicate/blink, but these are the fun ones in UR that fit a curve without thinking too hard. Leave a comment if you have a suggestion.
