The effect is sadly not particularly useful, since changing the colour of a creature card doesn't matter that much to account for Shyft's poor stat-to-mana ratio
Cards similar to Inari Fire include Fire King Avatar Barong, Fire King Avatar Yaksha, Brushfire Knight
I would only use Stunted Growth as a SB option
Since many of Dredges creatures enter from the graveyard, most removal spells arent effective against them since theyll usually just come back a turn after you remove them
In this case, well give it the benefit of the doubt since most of the storm combos in decks built around this card dont really need it to work properly, but still
When this card is link summoned, you can special summon 1 Cosmic Horror monster from your hand, but you cannot special summon monsters from your extra deck until the end of the turn, except link monsters
