Celebi - looks fine. Not sure why you want to get rid of Leech Seed.. A more offensive Celebi should have:
-Calm Mind
-Psychic/Energy Ball
-Psychic/Energy Ball/Baton Pass
-Recover
or should be a Choice Specs set

Blissey
-Thunderbolt
-Ice Beam
-Softboiled
-Calm Mind

Delibird - ugh... an Articuno covered in napalm could probably do better.. but if you really want to use it, here are some options from AB's site:

Delibird @Choice Band
Jolly Nature
Ability: Hustle
-Aerial Ace
-Ice Shard
-Focus Punch
-Ice Punch

Delibird @Focus Sash
Jolly Nature
-Counter
-Thief
-Ice Shard
-Aerial Ace

both sets are geared towards competitive battling though..
and just because I found this so amusing, here's a set from Smogon:

[SET]
name: OU Bounty Hunter
move1: Aerial Ace
move2: Brick Break
move3: Ice Shard
move4: Quick Attack / Focus Punch / Ice Punch / Rapid Spin
item: Life Orb
ability: Hustle
nature: Adamant
evs: 6HP / 252ATK / 252 SPD

<p>If you're a trainer with a sack as big as Delibird's, this is for you. This Delibird takes out two big OU threats, namely Tyranitar and Garchomp, in one hit. It outspeeds all and OHKOs most Tyranitar with Brick Break and does the same to most Garchomps with Ice Shard - although good luck getting it to hit through Sand Veil with the Hustle accuracy loss. Stealth Rock be damned - it goes in there, hits everything it can and dies. Perfect for fun anytime, on a Christmas themed team, or served stuffed with Oddish leaves and glazed in a sweet Cherrim sauce with ground Spelon Berries to taste.</p>

Pikachu @ LB
-Thunderbolt
-Grass Knot
-Substitute
-Thunder Wave

Hariyama
Ability: Guts
-Cross Chop
-Stone Edge
-Rest
-Sleep Talk
Rest to activate Guts, then ST to hit even harder with CC and SE
