I figured this out myself before seeing anyone else play it so i am a bit proud of that.
This is currently the strongest way to build beasts,it is very strong!.
Macaw reborn.
Tier 5 deathrattle reborn beast
Barron
Bird that buffs beasts with +1+1when beast takes damage
Tier 4 bird that gains 1 hp when beast takes damage
Multiples of the above.
These are the cards you want. You do not want the silly goose from t2 because it will ruin your reborns. With this setup you get way and way more procs then you would ever get with the rammer+goose build.
Macaw is also relatively easy to get golden. With barron+taunt aoe it then is 4 aoe already compared to 2 aoe for golden rammer (and if you reborn both and they go off the difference would be 8 aoe vs 4 aoe).
Its very strong,your beasts go 100-100 + quiet easily even without many goldens.
You absolutely need:barron,t5 dr beasts , t5 bird,macaw. The t4 beasts can be replaced with other aoe cards if you have more birds.
