What are similar black and/or white permanents to Divine Visitation?

Question

For my Commander deck I'm looking for black and/or white permanents that have similar mechanics to Divine Visitation and Teysa Karlov, respectively:

If one or more creature tokens would be created under your control, that many 4/4 white Angel creature tokens with flying and vigilance are created instead.

Creature tokens you control have vigilance and lifelink.

I'm looking for cards to buff my tokens, preferably enchantments but creatures will also suffice. By "buff" I mean: increase the statistics and/or add keywords to the tokens. Similar to the cards above, but the buffs may vary.

As a sidenote: any tips on how I can conduct such research by myself––such as a website––is greatly appreciated.

Answer 1

The Advanced Search on Gatherer may help a little.

For buffs that work when a creature enters the battlefield, search for "creature enters the battlefield under your control".

E.g. Cathars' Crusade:

Whenever a creature enters the battlefield under your control, put a +1/+1 counter on each creature you control.

For permanent buffs, search for "creatures you control get" or "creatures you control gain":

E.g. Benalish Marshal:

Other creatures you control get +1/+1.

Answer 2

Others have already pointed out good abilities. I'll mention Requiem Angel, which states:

When a non-spirit dies, you put a 1/1 spirit token into play instead.

When your Divine Visitation is on the battlefield, this effect is replaced by creating a 4/4 flying angel token instead. Since it's not a spirit, when that creature dies, Requiem Angel's ability will trigger and create a new 4/4 angel in its place.

With Teysa Karlov out in addition to these cards, each time an angel dies your board creates two more angels.

Answer 3

The official online resource for searching cards is Oracle.

Gatherer is guaranteed to have the official wording of all magic cards and offers both simple and advanced filtering options.

108.1. Use the Oracle card reference when determining a card’s wording. A card’s Oracle text can be found using the Gatherer card database at Gatherer.Wizards.com.

As far as your question is concerned, assuming you are asking about Standard, here are a few searches to start you off:

"Creatures you control"

"Whenever a", creature, enter, battlefield

Answer 4

There's an established Modern deck called B/W tokens. It's not a top deck, but it's there.

Key token cards are:

• Lingering Souls - a powerful card, makes 4 flying tokens over two turns.
• Spectral Procession - makes 3 tokens for 3 mana.
• Intangible Virtue - buffs all tokens.
• Bitterblossom - makes tokens every turn.
• Hidden Stockpile - same as above.

Other payoff cards include Sorin, Solemn Visitor, Gideon, Ally of Zendikar and Zealous Persecution. You could also run something like Honor of the Pure if your tokens are white (warning: too many anthem effects can mean you open a hand with no threats, in which case all your anthems are dead).
