Deathtouch Question

[BlackJester]

Now if you attached {Lifelink} to a {Sunhome Enforcer} then its basically double lifelink since the Enforcer is a triggered ability

True.

Stacking in the sense of a 1/1 having lifelink and then lifelink again with say, {Baskalisk Collar} , you wouldn't gain 2 in any circumstance?

"Equipped creature has lifelink and deathtouch." the creature would give you life not the collar. But since it already has lifelink it basically only gets the deatgtouch from said collar.

Multiple instances of lifelink are redundant, like having flying twice or trample twice. But Older cards kept a different wording that does stack.

like if a card says it gives a creature +1/+1 it is different than a +1/+1 counter. Sort of the same thing with lifelink it's all in the wording!!!!?!!?!!!??!!,!?!?!?!?!?!??'nv c !!?!?!!?!?!?!?!?!?!?!!?!?!?!?!!??!!?!?!!?!!?!?!?!?!?!?!?!!?!!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!!??!!??!!?!!?!?!?!!??!!??!!?!?!!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!!??!!??!!?!!?!?!?!!??!!??!!?!?!!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!!??!!??!!?!!?!?!?!!??!!??!!?!?!!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!!??!!??!!?!!?!?!?!!??!!??!!?!?!!!?!??!!??!?!!?!??!$?$?$?!?!(!(!(!($(!($(($$?!?!?!?!?!!?!!

We've come a LONG way from Deathtouch. If you are ever unsure, check out the Oracle text. If it says "lifelink", then it'll happen only once at the exact same time as damage happens.
If the card kept its trigger, like on the original {Spiritlink} it happens as a trigger after damage. There are some differences between the two. 
Lifelink ALWAYS gives life to the creature's controller, but you could enchant your enemy's creature with {Spirit link} and YOU'D gain the life instead.
If the bad guys are attacking for lethal damage, if you block with a lifelinker, you'll gain life at the same time damage is deal and live. SL will only trigger AFTER damage, you will die.
Multiple SLs will each trigger separately because they are triggers. Lifelink is a static replacement effect that replaces damage with damage+life.
