You don't need them, more often than not. The strongest cards have good effects.

But I'll give you what's used in the current metagame:

Dark armed dragon (Sometimes a staple, but not really.)

Judgement dragon (Thanks to the LS's self-milling effects and that this hasn't even been TOUCHED yet, plus it's summon condition isn't a cost, this card's why LS are going to be going up in this format)

Coelacanth (This is my personal opinion, really .x3 Just use that effect + united we stand and then something like raregold armor and you'll be set with a 6200 ATK monster which is the only thing your opponent can attack). My deck used DSF for an OTK last format. It was genius.)

I can't remember anymore since I'm tired. -shotdead-

But a few of the cards are banned in the advanced format, so just use some of the banned cards, like the two envoys and stuff. 8D

Blue Eyes White Dragon

Ultimate Baseball Kid - feeds off fire attribute monsters

Raging Flame Sprite – takes a few turns to charge, but can attack directly at any time

VWXYZ - Dragon Catapult Cannon

Dark Paladin

White-Horned Dragon

Gate Guardian

Ancient Gear Golem

Cyber End Dragon

Elemental Hero Shining Flare Wingman – 2500 atk + 300 for each elemental hero in your graveyard; at least two are in your graveyard after the summon (fusion)

Cyber Ogre – If at least 2 are in the deck total – one on the field, one in the hand

For free – Here are some monsters that can destroy the above through effects:

Man-Eater Bug

Snipe Hunter

well here are the cards that i know of that have some of the best stats or can have easily.

Great Maju Garzett - Tribute 1 monster get 2X the original atk of that monster.

Red-Eyes Darkness Metal Dragon - 2800 that can Special Summon itself from hand by Removing From Play 1 Dragon-Type monster on field and then may Special Summon one Dragon-Type monster from graveyard or hand that isnt Red-Eyes Darkness Metal Dragon.

Goyo Guardian - 6* Synchro with 2800 attack that can Special Summon a monster it destroys by battle and sends to the graveyard.

Dark Armed Dragon - 2800 that can be Special Summoned by having exactly 3 Dark-Type monsters in the Graveyard that can destroy a card on the field by Removing From Play a Dark-Type monster in your Graveyard.

Gladiator Beast Heraklinos- a 3000 beatstick that has the ability to negate and destroy any spell or trap (other than counter traps) by discarding a card. (Look up Gladiator Beasts if you don't know they are very easy to get this guy out in a couple of turns)

The 2800 monsters might not be 3000 atk power yet they are more powerful then just about any 3000 you'll find.

Blue Eyes

Dark Armed Dragon

Thought ruler archfiend

Hamon Lord of Striking thunder

Rainbow Dragon

Vampire Genesis

Neo Parshath the Sky Paladin (my personal fav as he gains attack equal to the diff in you and your opponents life points).

There are many more that i do not care to list, however strong attack is not everything it is more about their effects.
