Boardwipe Protection

Hi,

I built this deck around manifest dread with lots of interaction on creatures, so I hit creatures with manifesting more often than not.

It ran great up to now, but my achilles heel are boardwipes, as I only have Sapphire Dragon or Shell Crab to negate a spell.

Yet I dont want to increase the number of sorceries/instants more than necessary to add [[Heroic Intervention]] or [[Counterspell]]... Teferis Protection is deemed a Gamechanger in my playgroup

Do you have an idea, what I should add to get around such situations? (so I m basically looking for boardwipe protection on permanents i guess)

I saw [[Faiths Reward]] which i honestly consider, as it just will win me the game after a wipe, returning all my stuff faceup and with ETBs. But are there others like it (on permanents at best)? I guess [[Semesters End]] works, but is also a instant... [[Guardian of Faith]] seems great as well as [[Boromir]]...

Are there good counterspells on permanents apart from [[Fear of Impostors]] or this simic snake?
