Glissa, Herald of Predation generates a good board presence over multiple turns
Cross Duel release date
Instead of stacking +1/+1 counters, perhaps the new version would allow you to distribute -1/-1 counters, making this card deadly to creatures as well as other permanents on the board
But its ability immediately makes the high value completely worth it
Its effect does not activate when you summon it therefore its effect to summon can not be negated, only the summon can
Hiu ng gc (EN): When a Spell/Trap Card, or monster effect, is activated that includes an effect that Special Summons a monster(s): Return to the Extra Deck, 1 face-up Fusion Monster you control, or 2 Fusion Monsters in your GY, that mention "Fallen of Albaz" as material, and if you do, negate the activation, and if you do that, destroy that card
